Question 138Electricity & Electronics - QMED
70% to passA capacitor is to be tested with a digital multimeter set up to measure ohms. If the meter is connected to a shorted capacitor, how would the meter display respond?
Aimmediately display a value of OL with the value then continuously dropping to a low value
Bimmediately display a value of OL which remains at OL
Cimmediately display a very low resistance value which remains low
Dimmediately display a very low resistance with the value then continuously rising to a value of OL
AI Explanation
The correct answer is C) immediately display a very low resistance value which remains low. When a digital multimeter is set to measure resistance (ohms) and connected to a shorted capacitor, the meter will display a very low resistance value. This is because a shorted capacitor effectively acts as a direct connection, allowing current to flow freely without any resistance. The other answer choices are incorrect because: A) the meter would not display a continuously dropping value, B) the meter would not remain at OL (overload), and D) the value would not continuously rise to OL, as a shorted capacitor would consistently display a very low resistance reading.
