Auto Repair : How to Discharge a Capacitor

Discharging a capacitor means taking safety precautions and dissipating the energy from a capacitor into heat with a 12-volt automotive bulb. Safely dissipate the energy from a capacitor into the form of light with help from an auto mechanic in this free video on auto repair and maintenance.

    very smart way of doing it
    i am dealing whith campasitors around 330volts and 1000 farats (i dont know how to spell the word)the campasitors are charged at 600 volts and i want a lot of times to discharge it safely i was using 230 volts lamp but somestimes it burnet the lamp with out dischanging it if you have an other siply idia how to do this please answer

    Good vid. Educational, clear and short. Thanks, chomsky.

    ok how can i safely discharge on from a UPS? especially if it is soldered to a board?

    Try linking 2 or more 230v lamps in series.

    Why do you need a device that can handle more power when you use a capacitor with larger micro farad values? It doesn’t make any sense. From what I remember the farad and resistance determines the charge and discharge times. Therefore only a capacitor with a larger voltage rating should make you use a device with a larger power rating to discharge it.

    Thank you! I was thinking of a more safer way to discharge a Tesla coil, and this is by far the best way. I used a 180 watt bulb to rid of the extra voltage in the 5 bipolar capacitors. This is a great demonstration. Once again Thank you!

    i always use a 470 ohm 5 watt wirewound resistor to do such stuff. its better to slowly dischare a capacitor than fast like you are doing.

    good ol’ insulated screwdriver works well … hehe

    I’ve been shorting across them with a screwdriver for over a decade now and never damaged one or had one explode and I deal with the larger capacitors you’d find on a 7hp single phase motor’s start circuit.

    That’s the beauty of a capacitor .. there designed to dump there charge in a hurry … so why would it damage the capacitor …. sure rough on the screwdriver though … lol.

    We were actually taught to discharge them with a screwdriver across the contacts in the Navy. One guy forgot to turn the power off of the machine we were working on and he acquired the nickname…”Sparky”. That was something to see.
