And the value written over the body of the terminal is 250uF. That means the capacitor is working in good condition. This is the best way to test a running capacitor. Test 2: The second way to test a Running Capacitor. When you find your capacitor; this procedure to test a running capacitor is quite dangerous; it can give you an electric shock.
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its ...
Set the multimeter to measure capacitance. Most digital multimeters use a symbol similar to –|(– to signify capacitance. Move the dial to that symbol.
