Question

In an AC series circuit, the instantaneous current is zero when the instantaneous voltage is maximum. Connected to the source may be a [more than one option may be correct]

• A. pure inductor
• B. pure capacitor
• C. pure resistor
• D. combination of an inductor and a capacitor

Answer 1

Answer: (A), (B), (D)

The correct options are
A pure inductor
B pure capacitor
D combination of an inductor and a capacitor

This will happen only if phase difference between current and voltage be $\frac{\pi }{2}.$
Phase difference be $\frac{\pi }{2}$ in case of pure inductance,pure capacitance or a combination of capacitor and inductor.
So A,B & D is correct answer.
