For a good 0.05 uF capacitor ohmmeter reading should___________?
Correct answer: A. show low resistance momentarily and back off to a very high resistance
- A. show low resistance momentarily and back off to a very high resistance
- B. show high resistance momentarily and then a very low resistance
- C. go quickly to 50 ohm approximately and remain there
- D. not move at all
Explanation
A discharged capacitor initially conducts like a low resistance, so the ohmmeter reading starts low. As the capacitor charges from the meter battery, the current falls and the reading rises toward a very high resistance.
