Answer:
Reactance of the capacitor is 0.01 ohms.
Explanation:
It is given that,
Capacitance of the capacitor is 0.5 F
Peak voltage of the battery is 2 V
Angular frequency is 200 rad/s
We need to find the capacitive reactance. The capacitive reactance is due to the capacitor in the circuit. It is given by :
So, the reactance is 0.01 ohms.
