This animated way of teaching is great. I can actually understand what's being taught as it's being basically shown in action. Awesome stuff. Thank you.
That is literally the best explanation of voltage dividers I've run across, I've struggled to figure out how to apply Kirchhoff's law when figuring the resistance of two base-bias resistors in an NPN transistor, I can figure out one simple enough, but making a voltage divider for the base would make it more stable and thus I couldn't wrap my head around the math for figuring both resistors out. So thank you so much for that, count me subbed :)
You say that it's hard to find a resistor with 7.14 Ohm's resistance. Wouldn't it be possible to tune a potentiometer to that resistance instead of using the closest one available? Or is there any economical/technical issue with that? Thanks for the videos!
Well, potentiometers are expensive compared to resisters, and if you start to put a load and suck more amps through your voltage divider, it will change the characteristics and your volts might drop
Excellent explanation. I get it, but, remembering it is my problem.. I have to keep my Firefox bookmarks like a library of formulas.. It works for me.. A quick story : I went to school in 60's an 70's.. Learning was much more difficult cuz all we had was books and "a" teacher.. Both, teachers and books explain things in the way they think are best.. But if it wasn't right for you, You had few options.. Finding another book that explained it "Your way" was time consuming and frustrating.. They were only a couple of Teachers, at the most, and they were usually very busy.. Now-a-days, the Internet has lots of different teachers and text, to explain it the way you understand best. It makes learning stuff much easier. You can find what you need to know, in any way you need it.. Learning is fun again !
From the same generation, and totally totally right. Started electronics in 6th grade with Radio Shack Fairchild Heathkits. The only fast way to understand it was by figuring it out yourself, and reading books from city library. We definitely didn't have RUclips!

sorry if this is a silly question but if you wanted 5 volts for example. why wouldn't you just use a larger single resistor to drop from say 12 v to 5 then connect your load?
It depends on what your load is, voltage dividers are generally for very low current applications such as a reference for an IC, where current will be minimal and quite stable.
Hi, thank you for your great videos, What i know about resister is it is resist current not volt, please correct me if i am wrong, and What is the name of the simulator you are using
Thank you, I was reading a guide on esp8266, and they showed the formula, and I did quick calculation, and realized that im getting two answers, if I swapped the resistor value, and your video discusses why its like that.
I love this series and it is quite helpful, but you lost me on this video. I get the math, but I just don't get the usefulness so it is hard for me to assimilate the information as useful. all of the previous videos seemed to me to do a better job. I am certain it will be clear as I move through and learn more, but wanted you to know about the experience I had. Thanks, and keep up the good work.
Correct me if I'm wrong, but that power rating would blow up those resistors at 5:11 ... I think? If P = V x I you would get a power rating 4.9 watts on the first resistor.
Thanks. I was having a hard time getting why. so basically the drop to 0V is evenly shared by all resistor units (Ohm). The drop across a single resistor device is the proportional drop per unit (Ohm) times the units in that resistor. :)
At the 4:10 mark of the video resistor 1 is 2 ohms and resistor 2 is 10 ohms. Then when he goes to work out the equation, resistor 1is 10 ohms and resistor 2 is 2 ohms. Does that make a difference? Thanx ahead of time. Good video
The 2 ohm resistor will always have 2v and the 10 ohm resistor will always have 10v, using the example circuit, regardless of the order of the resistors.
I feel "flow" is all about "charge". Conventional flow is the flow of positive charge. Electron flow, is clearly the flow of negative charge. So, conventional flow is the opposite to electron flow. As such, electrons are physically moving. They increase negative charge at their destination, and their absence increases positive charge at their source. So negative charge flows with electrons, and positive charge "flows" into the absence of negative charge.
Fantastic, a channel that helps me, a software engineer, get into electronics! Q: why can't I just use this, rather than a buck stepdown converter? Is this less efficient? If so, is it significant if I'm just using it to step from 5 (arduino) to 3.3v (esp8266)?
Consider a voltage divider as "pass by value" to a function, as opposed to "pass by reference". You're supplying a voltage level to your circuit without changing the current flowing through the R1+R2 divider. Say if you use V2 as the input to an OpAmp. If you connect a circuit or component that DOES draw current, parallel to R2, then that WILL change current through the R1+R2, through R1, and the circuit changes. This is like a "pass by reference", which causes a change in the scope of the "calling" portion.
With regard to wanting a particular voltage from a voltage divider (3:48 in the video, trying to get 5 volts across R2), rather than calculating the value of R2 relative to a given R1 of 10 ohms (resulting in a very hard-to-find 7.14 ohm resistor needed for R2), couldn't you just replace the 10 ohm resistor (R1) with a 7 ohm resistor and then change R2 to 5 ohms?
So does this interactive doohickey only work if you pay the $15? I add the voltage meter across a resistor in the circuit, but then I can't get it to play. Or is there a button I don't see to get the current flowing again?
Good day. I have a problem you may have the answer to. i have a 120w amplifier and a VU meter that is rated at 60w. This VU meter connects to the output of the amp. I was wondering if i could use a resister to cut my wattage in half to safely run the VU meter.
A VU meter is made with a resistor in parallel to the wire wound "motor" of the meter. It basically measures the voltage across the resistor inside the meter. That resistor has a capacity, and running a larger supply through it would break it. So you want to put an extra resistor in parallel with the meter, which will take 1/2 of the Power away. Then you're left with a VU meter which will read 1/2 of the true Power. Your scale would be wrong. The VU meter would work safely, but the reading would be inaccurate because the scale is 1/2 what it should be. Check out some videos on shunt resistors to see how voltage is calculated according to current flow through a resistor, and you will understand how the VU meter works. Apply that knowledge to be able to calculate the necessary resistor to use in parallel with the VU meter, and then try it out. If you get it to work, don't forget to somehow change the scale printed on the meter. Maybe you can find a data sheet for the particular meter which will tell you what the internal resistor value is, and just use the same value resistor in parallel with the meter.
Hi, When current passes through a resister, Isn't it the current which should change since we are providing a constant voltage source? Sorry if it is a dumb question.
@@userou-ig1ze because that is the assumption this circuit and formula makes. In the example circuits, the current IS the same through R1 and R2. It cannot be different, in these example circuits. If you use V2 (the portion of Vtotal, measured across R2) as the input to a Hi-Z (or high impedence) component (like an OpAmp), there will be "no" current flow, and so The total current through the divider network (Itotal) will not change, which is where this formula and such circuits are useful. If you parallel circuitry with R2, and it draws current, then Itotal changes, and this change occurs through R1, so I1 will change, and the whole calculation changes. Then you have to mess around calculating the effective resistance of R2 and the circuit part which is drawing current, using the total current through that part of the circuit (R2+parallel circuit) and pump those numbers back into the equation with R1 to get the actual voltage drop across R2. Or just use a Hi-Z component, and be happy.
Can’t seem to pull it up and make it work. I downloaded the latest version of Chrome but still cannot get it to work is this application? Thanks. Excellent videos I think I put everyone I’ve been my favorites. Totally helpful thank you so much
May I ask that´s the ground needed for, if we anyway already have a negative-power-source-pole? And what did all the fuzz bring us after all? I mean, wasting my electricity over 1, 2 or 3 resistors won´t matter for me (and the exact mode/proportions of this wasting), as long as all I cared about, was to waste electricity. Where can one connect something on this circuit, in order to make it have some utility?
Very helpfull, just one question. Say you have resistors of 1 - 10 ohm, only rounded numbers. Is there a method to calculate if there is any way to get the desired voltage with round numbers, treating both resistors as a variable, but rounded. And if there is, how do you do it? I know in practice this will probally never be a big problem, but I can imagine if you have really fragile equipment it might be.
I'm not quite sure I understand the question correctly. But, if you want to know the resistance of both resistors to get a desired voltage, there isn't an equation that will tell you what both resistors should be. However, you can work out the ratio between the two. First you need to know, supply voltage (Vin), and the desired voltage across a resistor(Vout). Ratio = Desired Vout/(Vin - Vout). If my supply voltage is 12V and desired voltage is 5V. Ratio = 5 / (12 - 5) Ratio = 1.4 I now have the ratio, but I still need to chose a random value resistor. Let's say I choose 10ohms for R2. Because the ratio should be 1.4, R1 should be 1.4 times the resistance of R2. In this case, R1 = 10 x 1.4. R2 = 14ohms. If we now work out the voltage across R2... V = (12v/24ohms) x R2 R2 Voltage = 5v If you need rounded numbers and you get decimal answers, just round the result up or down to the nearest whole number. Your voltage won't be truly accurate, but good enough. There are different voltage dividers such as accurate potentiometers that can provide much better accuracy and variable resistance. Sorry if i didn't adequately answer your question.

I want to modulate AC and DC voltage by using voltage divider, means two sources AC and DC. Output should be about 0.6A. How can I select the Resistances ?
Use Ohms law. You know the V and the I, so calculate the R. Once you know the R needed at the point of measurement, you can then also calculate the 2nd R value to make up the divider circuit you need.
A voltage divider is all about getting a specific voltage level to part of your circuit. A Linear Voltage Regulator supplies both Voltage and Current to the circuit. You use a voltage divider to set a voltage level to supply a component which "draws no current" like the input of an OpAmp.
This is by far the simplest explanation of voltage dividers on RUclips. A natural teacher giving only facts that are useful, no BS on this channel.
