Question

The capacitive reactance in an A.C circuit is:

• A. effective resistance due to capacity
• B. effective wauage
• C. effective voltage
• D. None of the above

Answer 1

The correct option is A effective resistance due to capacity

Capacitance in an AC circuit is constantly charged and discharged. As the AC supply voltage increases and decreases the capacitor charges and discharges with respect to this change

We know the current flowing through the capacitor is in opposition to the rate of change of applied voltage. Like resistor in a circuit$,$ the capacitor as well offers resistance against the flow of current in the AC circuit which is termed as Capacitive reactance

Capacitive reactance depends on the capacitance of the Capacitor it is given by following expression $X_C=\frac{1}{2\pi \times fC}$

Thus the capacitive reactance in an A.C circuit is the effective resistance due to capacity

correction option is $B$
