Discharging motor start capacitors
WebAt the start of the discharging process, the initial conditions of the circuit are: t = 0, i = 0 and q = Q. The voltage across the capacitors plates is equal to the supply voltage and V C = V S. As the voltage at t = 0 across the … WebTo test a start capacitor, we perform the following steps-. We point the knob to capacitance mode. Then any of the multimeter probes are held with the negative terminal of the capacitor, and the other probe is attached with the positive terminal firmly. The multimeter screen will now display a value.
