The correct answer is: D. Leaky
When testing a capacitor with an ohm meter, the capacitor should show a high resistance reading at first, then the resistance should decrease as the capacitor charges. If the resistance reading never decreases, or if it decreases to a very low value, then the capacitor is leaky.
A leaky capacitor is one that has a small amount of current flowing through it even when it is not supposed to be conducting any current. This can happen due to damage to the capacitor’s dielectric material, or due to a defect in the capacitor’s construction.
A leaky capacitor can cause problems in electronic circuits. For example, if a leaky capacitor is used in a filter circuit, it can allow noise to pass through the filter. If a leaky capacitor is used in a power supply, it can cause the power supply to provide an unstable output voltage.
If you suspect that a capacitor is leaky, you can test it with an ohm meter. To do this, set the ohm meter to the highest resistance setting. Touch the ohm meter probes to the capacitor’s terminals. The ohm meter should show a high resistance reading at first. Then, as the capacitor charges, the resistance reading should decrease. If the resistance reading never decreases, or if it decreases to a very low value, then the capacitor is leaky.
