Question

Choose the wrong statement of the following :

• A. The peak voltage across the inductor can be less than the peak voltage of the source in an LCR circuit
• B. In a circuit containing and a capacitor and an ac source the current is zero at the instant source voltage is maximum
• C. When an AC source is connected to a capacitor, then the rms current in the circuit gets increased if a dielectric slab is inserted into the capacitor
• D. In a pure inductive circuit emf will be in phase with the current

Answer 1

The correct option is D In a pure inductive circuit emf will be in phase with the current

In pure inductive circuit,

voltage leads by $\frac{\pi }{2}$.
