Thanks. I connected a LED light to my alarm clock to see the analog tuner at night but it is never a constant light since it turns on and off based on the sound. Looks like a capacitor is what I need and I found one from an old rc remote.
@@OhmifyWhat was the value of Capacitor and how much volts was your battery? I'm unable to get this work with a 25v Capacitor with a 9v battery and 10k resistor. It works normally but not if I add the Capacitor
Thanks for the video! I've been trying to learn some electronics and every other video just explained how it works, without actually telling me WHAT it does haha. And don't get me wrong, I'm into that stuff too, I just wanna learn the basics first and the physics behind it later heh
Hi, how can i do this but the other way around.. ?? Basically, i want the led to slowly fade on when power is connected to the circuit ?? must i connect the capacitor in series ??
You'd need another resistor between plus from battery and positive side of capacitor. This will slow down the charging of the capacitor and hence make the LED fade in.
help me on this please!what type of capacitor do i need to buy in order to give a spotenious fade when i turn off the switch on a 12v 100watt halogen car lamp!
Hi there! I want to use a capacitor to stop a 12v small led flickering . I aimed to 16 v capacitor but not sure what UF to chose. Do you think 22 UF or 47 UF will do, or should I get a higher UF ?
I'm new to Electronics. Can i do this with 35v 1000uf capacitor? It's not going to explode into my eyes right? What value of your capacitor and resistor you used in this video?
Yes, you can. And you don't have to worry about it exploding as long as you use a standard 9V battery. (If you connect it to 110 or 230V, expect a small explosion). I think I used 1000 µF capacitor and a resistor of 470 ohms.
If i have a small solar panel. And the output is 5vdc can i add a cap. At the output to make it move of a stable voltage. . It will charge my phone but i am trying to make it work better with less Fluctuation on the output side.
Very much helpful. Can you tell me what volt-capacitor should i use for a 12 volt LED strip? I will replace my Yamaha keyboard's display backlight(ccfl) with LED. I will take the 12 volt power from any voltage regulator located in the power suplly board inside. Thank you
Hi Sir, I have a question. For touch screen switch and some smart light bulb, when you turn off the switch, the light bulb only dim and not completely turn off. but when a capacitor is added between the live and neutral cable, the light bulb is completely turn off. Able to illustrate what is the reason behind that?
How does this work? The capacitor is charged to the input voltage, which is connected before the resistor and bypasses the resistor entirely. Why doesn't the LED blow up?
If you look closely, when the camera angle is from almost directly above, you can see that one of the the capacitor's wires goes to the resister, which in turn goes to the LED. It is right at 0:25 in the video. BTW... If you use the comma and period keys, YT vids go frame by frame. It is easy to remember because the comma and period are on the '' keys. Don't use the shift key, though. Unless you want to speed-up or slow-down the playback speed. Also, the left ←and right → arrow keys jump backward/forward by 5 seconds.
@@RCFrizzit seems you are correct that when the voltage source is removed, the capacitor is in serial connection with the LED. However, the resistor is still present in the circuit and keeps the current below threshold level.
I want to ask, how can I maintain the arduino r3 running at 12v for 2sec while switching to alternate power source.(Note: I have the main power source producing 12v and a battery producing 12v too) the power module circuit is yx850 power failure system. There's a a delay in the module when switching
Just use a capacitor with enough capacitance, and you should be able to do that. How much capacitance depends on how much current your circuit is pulling. But you could experiment to find out how much you need.
In this example simply use a larger capacitance value for longer delay, smaller capacitance value for shorter delays. It would be possible to create a formula for this based on the capacitor charging formula.
The voltage on a capacitor is how much voltage it can handle. So you just have to make sure you don't have a capacitor with a voltage rating lower than what you plan to use. For the farad value - it depends on the time you want it to take to fade out. Higher farad value means longer time.
Because the LED strip pulls way more current than a single LED. So you discharge the capacitor much faster and the delay becomes so small that you don't notice. If you want to fade a LED strip, you should rather use a transistor in between.
You always connect a LED in series with a resistor. And as long as you do, you can apply any voltage you want. You just have to adjust the resistance value according to the voltage. More info here: build-electronic-circuits.com/current-limiting-resistor
A few differences: Inductors have very little capacity compared to capacitors. An inductor will resist change in current. Current can still flow through a charge inductor.

Amazing,
Ultimately I got this❤
Short and sweet
Thanks!!! I totally understand now!!!
A capacitor has two outcomes. First outcome is storing electricity as expected. Second outcome is💥
Very nice , the best .
I learned something new today
After doing this do we need to remove the capacitor and discharge it, or did it already get discharged when the led finally turned off?
When the LED turns off, it's not 100% discharged. So if you for some reason need to discharge it completely, yes, you'll have to do that manually.
can you add capacitor mid charge?? this would have solved the seinfeld episode problem w the arcade game
Thank you so much!
A question ✋🏻, can we use the LED without the resistor??
no, usually the voltage and current are so high that itll burn out
No, you should use a resistor to avoid damaging the LED.
What is the resistor you have used?
This video is so good
Thank you.

@@Ohmify in that case can we remove the other resistance in series with the led ?
@@temtamyassine2292 No, that one is needed for fading out

hey, how do I make a delay turning on the led?
Place a resistor (1k-10k) in between the circuit and the battery (in series).

I'm not sure really. I recommend just testing a few different values. But 22µF or 47 µF both seem like good values to start with.
Hi sir, do I have to add diode on Voltage input to protect dc circuit if ever I need to make bigger project? Thanks in advance. newbie here
A diode on the input is usually used to avoid connecting the power supply the wrong way - or to choose between two power sources.
I'm new to Electronics. Can i do this with 35v 1000uf capacitor? It's not going to explode into my eyes right?

The voltage rating must be higher than 12V, but there's no limit on how high. So choose any rating higher than 12V.

Which way to connect it polarity wise?
Plus pin towards the plus terminal of the battery.
What capacitor should i use with 12v1amp dc power adaptor with led to make slow dim effect after power off
As big as possible. The bigger, the longer the dim effect.
@@Ohmify thanks for the information. Soon I will try
Please do it with a Inductor also, then Inductor plus capacitor
You won't get enough delay to make it visible for the naked eye with an inductor unfortunately.
Resister value ?
1k almost always works. If you want to calculate it, check out this article: www.build-electronic-circuits.com/current-limiting-resistor/

amazing
Will this have same effect for 120V AC
No. With AC you would first charge the capacitor, then discharge the capacitor, then charge it, then discharge it, then... And so on.
what voltage of battery did you use?
9V
For what we need it?
One important thing is to add time delays into a circuit. For example to blink an LED.
why it is not working in LED strips?😢
Because the LED strip pulls way more current than a single LED. So you discharge the capacitor much faster and the delay becomes so small that you don't notice. If you want to fade a LED strip, you should rather use a transistor in between.
How much voltage to connect with led
You always connect a LED in series with a resistor. And as long as you do, you can apply any voltage you want. You just have to adjust the resistance value according to the voltage. More info here: build-electronic-circuits.com/current-limiting-resistor
how is this different from an inductor
A few differences: Inductors have very little capacity compared to capacitors. An inductor will resist change in current. Current can still flow through a charge inductor.
what about what does a capacitor do in a flasher circuit?
It adds delay to keep the LED on/off for a short time
❤❤❤
that is easy but how much value of capacitor we need.... and no one talks about it...
Try with 1000µF. It's possible to calculate it too, but a bit complex, so the trial and error method is usually faster for circuits like this.
Funny thing is I know what a capacitor does in theory but never seen one in action. Like sure store electricity but like what?
Please teach me how to make a DRAM with capacitors 😭
I don't know how to do that.
