Capacitive Reactance - The Reactance of Capacitors

WebA capacitor has two poles: a positive and a negative. They should be clearly marked on the capacitor. The positive connects to the same positive power lead that goes to your sub amp's positive, 12 volt, connection. Use the same gauge wire as the amp uses for its power. This can be accomplished with a distribution block. WebApr 10, 2024 · Capacitors go through a cycle of charging and discharging. One reliable way to test a capacitor is to use the ohmmeter function of a multimeter. Checking the capacitor’s resistance will tell us if it’s in working order. To do this check, we connect the ohmmeter’s probes to the capacitor’s terminals. ct sc icmarket
