To test a capacitor with a voltmeter, you need to follow these steps: Disconnect the capacitor from the circuit. As before, you need to make sure that the capacitor is not connected to any power source or other components in the circuit. Discharge the capacitor.
Low capacitance capacitors have low leakage current; thus, a low current ammeter can measure the current accurately. If the leakage current is high, the ammeter will not able to measure accurately due to the noise and unstability of the charged capacitor. Therefore, the second method should be used for higher capacitance capacitors*2.
1. How to test a capacitor without capacitance measurement If only a simple multimeter without a function for capacitance measurement is available, then only the rough functionality of the capacitor or electrolytic capacitor (electrolytic capacitor) can be checked.
To test a capacitor with resistance, you need to follow these steps: Disconnect the capacitor from the circuit. As before, you need to make sure that the capacitor is not connected to any power source or other components in the circuit. Discharge the capacitor.
There are several ways to test a capacitor to see if it still functions as it should. Disconnect the capacitor from the circuit it is part of. Read the capacitance value on the outside of the capacitor. The unit for capacitance is the farad, which is abbreviated with a capital “F.”
Check the capacitor’s voltage rating. This information should be printed on the outside of the capacitor as well. Look for a number followed by a capital “V,” the symbol for “volt.” Charge the capacitor with a known voltage less than, but close to, its rated voltage.
