Question

In an a.c. circuit contaming only capacitor, the phase differen between current and voltage is  

(A) \(0^\circ\)

(B) \(90^\circ\)

(C) \(180^\circ\)

(D) \(45^\circ\)

Answer 1

Correct option is : (B) \(90^\circ\) 

In an a.c. circuit containing resistance onIy voltage \(\&\) current remain in the same phase.

If circuit contains inductance only, voltage remains ahead of current by phase difference of \(90^\circ\).

If circuit contains capacitance only, current remains ahead of voltage by a phase difference of \(90^\circ\).

Answer 2

Correct option is (B) \(90^\circ\)
