Thank u prof. Years back I travel 30km to where school was to do this topic and while my friend seem to get it well, I only got it partly. Not too late yet now.
Hi everyone, thanks for you your interest! No, I'm not writing backwards. The secret is given here: ruclips.net/video/CWHMtSNKxYA/видео.html Cheers, Dr. A
That is a very special glass you have for teaching. I am studying for entrance exams for electrical and multi skill opportunities. I did these classes in the Navy Nuclear power program 30 years ago. Thank you for the Algebra update and a class well taught.
Current in a capacitor does not flow through it, charge pushes and pulls across it(like an inductor), that's why current moves at the capacitor at the moment in a battery circuit when its turned on or off....this always seems to me critical information that is left out. Thank you for being clear about this.
DR Anderson I have to tell you that I admire your job, I've understood and practiced everything I was supposed to learn in two weeks,thanks you, regards from colombia.
Nicely done. I've been in Physics since undergrad days (early 70s) and ham radio since the 60s. I still enjoy a lucid, well organized review of problems. I also teach elementary electronics for our prospective ham radio licensees. We do class work like you did here then go to the lab for hands-on application. I love the Learning Glass. I've just discovered the LearningBoard and have watched the webinars. Very nice teaching tool! Gotta figure out how to get one, but I don't have much budget. Retired, doing all this on a volunteer basis. Now if you need a beta tester for the newest model... :-). 73 de WA8YCD
Bob West. I am Ka3jnu and I am studying for my Extra Class and was watching this video and saw your post. You worked my husband Wa3tvh on 11/1/2021 for POTA. Sounds like you run some nice classes.
Does anyone else think this guy looks like Benedict Cumberbatch's twin brother? Except instead of Doctor Strange, he's actually... Doctor A? No?.. Well anyway thanks for the video! Crystal clear now.
at time 57:37 of the video, I1=I2+I3 and that's why there was a little bit error in the value for I3 that should be 0.15A instead of -0.15A. THANKS FOR THE VIDEO
Ham, Great question! You don't really know initially, but if you're consistent with applying the rules, it doesn't matter. You can pick either direction, and if you chose the wrong direction, you will end up with a minus sign. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
The video isn't mirrored. He just stands behind a special glass and writing on that glass like usual. People on the other side of the glass can also see the writings on the professor's view. It's just a special glass.
321reh, Remember that I3 is related to I1 and I2 through the equation shown in the video: I2 = I1 + I3. So if you just keep it as I3 through the 64 ohm resistor, you could equivalently write that as I2 - I1 through the 64 ohm resistor. Hope this helps. Thanks for watching and asking. Cheers, Dr. A
Thank You For Your Explanation!!! I Took This Subject 40 Years Ago And I Forgot Some Key Facts!!! A Very Good Explanation You Have Here DR.A!!!!( And A Great Video Too!!!)
At 42:40, how did he know that I3 was going to go down? It seems to me like if we look at the 58V battery, the current should be flowing from that into the 64Ω resistor, which would make it going up instead.
It doesn't really matter from which battery you decide to flow the current as long as you use kirchoffs correctly. Its just that calculations are easier if you choose the one with higher potential difference
athantas, Great question. Current sources tend to have constant current (varying the voltage), whereas voltage sources tend to have constant voltage (varying the current). Most devices like batteries or wall power act like a voltage source. Thanks for the comment, and keep up with the physics! You might also like my new website: www.universityphysics.education Cheers, Dr. A
... your'e a legend Matt. You have empathy for those of use that never qualified to do calculus at school but are not stupid. Do you have any tuts. where you explain the elements and applications of the differentail and integral calculus ... your way ? :-)
hi just wondering i got taught a different symbol for a resistor it was more like a box which one is correct. Another question when do you do live streams?
So if I have a schematic all I have to do is find equivalent resistance? What about the other components? Do I just ignorthem? I'm mean like transistors, opamp, ic.
I think i saved a liion lithium battery that was over charged 5v instead of 4.2 its a 3.7.. I just charged it at like 2.3 and when intead of waiting till it reaches 4.2 i just waited till it bropped to 4.2...was thinking is if equal balancing same length of power equals same power. Also was controlling the volt with a pwm controlled for a motor. The controller changes slightly when using multi-meter and was strange as you mentioned how resistance is how electronics function so it was changing pwm output when re measuring. I used a motor that used same amount of power as controller to set the mark on the dial. Hope this is making sense to someone and helps make more sense.
Hi, in relation to the last section (the exercise at the end of the vid) i have a similar problem which has 3 batteries and 3 resistors (3 loops in total), i have the values for the batteries but not the resistors, i am supposed to find the voltage of one resistor. and do not know where to start to tackle this problem. Can you help?
+Terry T You'll have to use Kirchoff's rules, just with three loops instead of two. Rules: 1) Voltage drops around any closed loop is zero. 2) Currents don't pile up at intersections. Good luck, Dr. A
Fair point. We know that it's electrons that are moving. So when they move away from one side of the capacitor, they leave behind some unpaired positive charge. Cheers, Dr. A
Zuber, Excellent point! You are indeed correct that for ideal circuit elements with R=0, the time constant τ = RC = 0. The capacitor would charge up (or discharge) infinitely fast. Of course, this is only the case when all R=0 in the circuit, including the wires and the voltage source. Any real wire (not superconductor) has some finite R, and any voltage source (like a battery) has some internal R. Thanks for the comment and keeping me honest! Cheers, Dr. A
on a solar charger I made if you measure the voltage after the diode while the circuit is open there is 0 voltage drop. once you put a load on the circuit the voltage drop is 0.2-0.3v. is there a reason for this?
+micheals1992 I would need to see the circuit diagram and where you are measuring the voltage. But basically remember that since V=IR, if there is current and resistance, there is a voltage drop. When the current is off, there is no voltage drop. When the current is on, there can be a voltage drop - including in the wires themselves since wires still have some small resistance. (Diodes themselves have a built in voltage drop, but this is usually closer to 0.8V.) Thanks for the question! Hope you're enjoying physics. Cheers, Dr. A
Matt Anderson It's a Schottky diode which is why the v drop is low (multimeter says 0.2v in >l mode). it's a pretty basic circuit and the diode is only to prevent discharge during the night. I recently got a multi meter and I decided to make a solar AA/AAA battery charger while playing around with some parts I had and I found it interesting that the diode only had a v drop when a battery was connected. I'm also making a DIY Velocycle and wanted to make an indicator system and a central power system for all the lights etc which is why I'm trying to learn a bit about electronics before the summer comes and I finish my project for this years bike show. thanks anyway! :)

I'll probably put an isolation switch on the battery for when it's not being used.
Hi Matt. On the problem, how did you determine the direction of the current in the middle path without doing any calculations yet? I am sure it's obvious and I am just missing it... Thank you!

Is a bit wrong to say that positive charge is going to on side of the capacitor, unless they are Hydrogen nucleous in a fuel cell.
Fair point. We know that it's electrons that are moving. So when they move away from one side of the capacitor, they leave behind some unpaired positive charge.
Cheers,
Dr. A
But the capacitor get instantly charged when no resistance in circuit so at t=0 there is no current

if the value for the current is negative does that not mean that you've chosen the direction of the current in the circuit wrong? i'm so confused.
Yes. Just pick a direction for the current and if your answer turns out negative, the current is going the other way.
