Question

If the leads of an ohmmeter using the R X 100 scale are placed on the terminals of a capacitor and then reversed, the needle does not move. This would indicate that the capacitor is ___.

A. Charged
B. Discharged
C. Faulty
D. Normal

Answer 1

The capacitor is discharged. This indicates that the capacitor is discharged (B).

Step-by-step explanation:

This indicates that the capacitor is discharged.

An ohmmeter measures the resistance of a component. When the leads of an ohmmeter using the RX 100 scale are placed on the terminals of a capacitor and then reversed, the needle does not move. This means that no current is flowing through the capacitor, indicating that it is not storing any charge and is therefore discharged.

A charged capacitor would show some movement of the needle because it would allow current to flow through it, indicating that it is storing charge. A faulty capacitor might show erratic readings or no readings at all. A normal capacitor would show consistent readings, but on the R X 1 scale instead of the R X 100 scale.
