[435] How to Discharge a Capacitor - Capacitor Safety

in this video i demonstrated How to Discharge High Voltage Capacitor in SMPS. because in some circuits the smoothing capacitor / bulk capacitor / main dc capacitor holds the charge, even the the circuit is disconnected from the line. if for test purpose we want to touch the circuit or we want to replace some component, it becomes very dangerous and it may cause severe electric shock

This is quickly becoming one of my favourite electronics channels. I’m just learning electronics in my retirement and I need people who explain the very basics with no assumptions of knowledge.

Sir, iam a basically a mechanical engineer, after watching your videos, now become electronic engineer, thanks for your videos, I need wiring diagram for fanuc power supply module

[xbullshet]

Wery simple and very useful. I was discharging capacitors with screwdriver and hate the pop and welding on tip of screwdriver etc. Thank You! Good and easy to understand video!

[garrettsitas]

This IS GREAT. Very simple, strait forward, but well explained.

[ginogarcia]

That was so amazing and simple and straight to the point. Great stuff sir

Im a newbie in this field but watching all your videos im becoming pro 😊😊😊 in less than a time thank you sir for all your demonstration n information you deliver

I was just looking for designs for this device and there you are in my subscriptions; perfect timing! Your design is unique in that it allows the voltage to be conveniently observed with a multimeter. You have me thinking on clever designs for my build. I have an extra volt meter that is not so valuable. I think that I will make it a dedicated capacitor discharger, by placing the resistor across the probe pins, on the PCB. That will make for a neat, professional package. I am excited! Thank you for the inspiration!

This channel deserves way more subscribers.

Waow thanks for the knowledge. You always have a video for any problem I face. Am a beginner and I always face so many challenges and doubts since I no one to learn this from aside youtube.Keep up the good work.

Great information ways you are such an excellent teacher 👍🇬🇧🇬🇧

[gopalarao]

Very good idea and very very cheap to make it to all technical people

[tonyhenson]

Brilliant Jo my friend, can you use the resister on any size capacitor or have you got to go up in size . Thanks

Tony

Amazingly useful video
Big Like from London 🇬🇧👍

I have a question. I have a 10 ohm 100 watt resistor that I use for discharging capacitors. This discharges the capacitor very quickly with no sparks but
will I cause damage to the capacitor by using such low resistance?

Salam M Hasseb, nice video !
I did a mistake while desoldering a bulk capacitor in an atx psu and i don't have any output anymore, can you show how to play with opto coupler to force the startup. Thank you.

Just wanna add something. If you use Fluke Meter, Testing Charged Capacitors directly using capacitance test, the tester will display diSC indicating the multimeter is discharging the capacitor before it measures the capacitance. Fluke 87V has this feature and been using every time I encounter a capacitor that might be charged.

Thanks 😊 master Thank you so much this video very very useful for myself Thank you so much Brother 💓 😊 😀 ☺️ 🙏 💜

[Kchess]

Thank you, you explain this very well. I got a small shock from a small capacitor in a camera once. I am going to replace some relays in a hi-fi amplifier soon that has large capacitors. I am definitely going to take your advice and check the voltage and discharge the largest capacitors before working on the board 👍

Took out MBO from Grunding TV after i tested TV with no picture output and no turning on at all but got few times glimpses of picture and it was black screen again after that . There was one big capacitor (450 V, 68 μF ) on it and was laying down and was some black "gummy" substance under it . I suspected it was probably leak of electrolyte from capacitor and while holding MBO i touched 1 pin where power cord was connected and got pinch of electricity XD through thumb all way to the shoulder . Video is awesome friend and i have question . Can i damage digital instrument for measuring capacity if it is larger ( for example 68 μF ) then on instrument, which is 20 μF highest value for measurement on instrument ?

Great video, I'm going to build this.
