WebThe product of the resistance (in Ohms) and capacitance (in Farads) is the scale time for the discharge (to go to 1/e of the original charge): t = RC. With V = Q/C and I = V/R = Q/t, you can also solve for the minimum resistance to keep the discharge current to a safe value. WebDec 7, 2024 · Turn the power of and short the terminals with a screw driver. That's actually quite dangerous. A 5W, 1kΩ resister is far better. If you're going to use a screw driver anyways, make sure your face is not line of sight of the screwdriver, along with the least amount of your body as possible.
WebUse wire strippers to strip 5mm (1/4″) of insulation from one end of each wire. If you use a set of probe leads for the discharge tool, only strip the wire side of the leads. Shorten the resistor leads. They need to be about the same length as the exposed copper on the wires.
