Question 122Electricity/Electronics - 1st Asst/Chief70% to pass
Which of the following statements represents the reading display of a hand-cranked megohmmeter when testing a capacitor start motor start capacitor in good condition that has been properly discharged prior to the test?
AI Explanation
The correct answer is A) The needle should immediately deflect to a very low resistance value and then gradually increase to infinity while cranking.
This is correct because a capacitor start motor start capacitor in good condition that has been properly discharged prior to testing will initially show a very low resistance value, indicating the capacitor is charged. As the megohmmeter is cranked, the needle will gradually increase to an infinite resistance value, indicating the capacitor has fully discharged.
The other options are incorrect because: B) would indicate a short circuit, C) would indicate an open circuit, and D) would not accurately reflect the gradual discharge of a properly functioning capacitor.
