Discharging large capacitors
WebApr 22, 2014 · There are three different ways to discharge large filter capacitors in a power supply: with a screwdriver, the leads of a socketed 100 watt light bulb, and the leads of a high-wattage resistor. Using a screwdriver to discharge the capacitor is not recommended because you can generate a spark and damage the printed circuit board … WebA large charge stored means that there is a large pd across the capacitor; this makes a large current flow, so the charge decreases rapidly. When the charge is smaller, the pd …
