When testing a capacitor with a digital multimeter set up as an ohmmeter, what would be the indication on the display when testing an initially discharged capacitor in good condition?

Athe display would immediately show very low resistance but gradually climb to 'OL'
Bthe display would immediately show very low resistance but rapidly climb to a slightly higher value and remain there
Cthe display would immediately show very low resistance and remain at this value
Dthe display would immediately show 'OL' ohms and remain at this value
AI Explanation

The correct answer is A) the display would immediately show very low resistance but gradually climb to 'OL'. When testing a capacitor with an ohmmeter, an initially discharged capacitor will initially show a very low resistance as the meter measures the charging of the capacitor. However, as the capacitor charges, the resistance measured by the ohmmeter will gradually increase until it reaches the 'OL' or open-circuit indication, signifying that the capacitor is now fully charged. The other options are incorrect because B) the resistance would not remain at a slightly higher value, C) the low resistance would not remain constant, and D) the meter would not immediately show 'OL' for a good capacitor.
