If a run capacitor is tested and the meter needle moves toward 0 and then back to infinity, what can be concluded about the capacitor?

• A. The capacitor is faulty
• B. The capacitor is good
• C. The capacitor is partially defective
• D. The capacitor is for motor start only

Answer: (B)

When testing a run capacitor with a multimeter, observing the needle move toward 0 and then return to infinity indicates that the capacitor is functioning properly. A healthy capacitor will momentarily register a low resistance value as it charges, which is reflected in the needle moving toward 0. As the capacitor fully charges, it will eventually show an infinite resistance, demonstrating that the capacitor can store energy effectively and is not leaking current. The behavior observed aligns with the expected performance of a functional run capacitor, which is designed to assist in maintaining consistent motor performance by storing and releasing electrical energy. Therefore, the conclusion that the capacitor is good is supported by the meter's readings during the test.
