To test a capacitor set the multimeter to OHM and touch the leads of the multimeter to the terminals on the capacitor. The multimeter should read to infinity, indicating that the capacitor is in good condition. This meth... More » Home & Garden Home Maintenance Electrical

To bench test a start or run capacitor in a home appliance or other electrical equipment, use a multimeter to measure the unit's capacitance — how much electrical charge it can store. Check the capacitor's capacitance an... More » Home & Garden Home Maintenance Tools

You can test an electrical capacitor by using an analog or digital multimeter. The first step is to disconnect the capacitor from the electrical source. Visually inspect the capacitor for any signs of leakage or bulging ... More » Science Physics Electricity

To wire a motor starting capacitor, connect the motor's positive terminal to the resistor and connect one of the resistor's terminals to the capacitor. Identify the manufacturer-defined start, run and common connections ... More » Home & Garden Home Maintenance Electrical

To start electric motor start and run capacitors on a single phase motor, turn the switch fully clockwise and then release the switch. While both capacitors engage at start-up, the start capacitor runs only momentarily. ... More » Home & Garden Home Maintenance Electrical

A series combination of capacitors is reduced to a single capacitor by adding the sum of the inverses of each individual capacitor, then inverting that. The equation is C_eq = (1 / ((1 / C1) + (1 / C2) + (1 / C3) + ... +... More » Science Physics Electricity

The purpose of a capacitor is to store energy in the electric field between a pair of closely spaced conductors that are called plates, and these capacitors are used in electrical circuits as energy-storage devices. Capa... More »
