Question

What happens to the current if the frequency is doubled while the applied voltage and capacitance stay the same?

पर्याय

• The current is halved.

• The current is doubled.

• The current is unchanged.

• No current flows.

Answer 1

Doubling the frequency halves the capacitive reactance. Since \[I=\frac{V}{X_C}\] and the voltage stays the same, the current is doubled.
