[amp_mcq option1=”has no effect on the total circuit current” option2=”doubles the amount of total current” option3=”cuts the total current by one-half” option4=”thrice the amount of total current E. None of the above” correct=”option2″]
The correct answer is: B. doubles the amount of total current.
A purely capacitive circuit is a circuit that contains only capacitance and no resistance or inductance. The current through a capacitor is proportional to the rate of change of the voltage across it. This means that if the operating frequency of a purely capacitive circuit is doubled, the current through the capacitor will also double.
Option A is incorrect because doubling the operating frequency will cause the current through the capacitor to double.
Option C is incorrect because doubling the operating frequency will cause the current through the capacitor to double, not cut it in half.
Option D is incorrect because doubling the operating frequency will cause the current through the capacitor to double, not triple.
Option E is incorrect because doubling the operating frequency will cause the current through the capacitor to double.
