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. WebSome capacitors are defined by a three number code followed by a letter. This letter represents the tolerance of the capacitor, meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. The tolerances are indicated as follows. Read B as 0.10 percent. Read C as 0.25 percent.
