Capacitor Characteristics
It is common for capacitor run, or capacitor start, capacitors to have a nominal value within a range, and have tolerances of up to +/-10% since they are cheaply made. Single phase electric motors generally need a start capacitor to energise a second phase winding for motor starting for a very short period of time. Start capacitors therefore have larger capacitance values than the …
