Question

In an AC series circuit, the instantaneous current
is zero when the instantaneous voltage is
maximum. Connected to the source may be a
(a) pure inductor & pure resistor
(b) pure capacitor & pure resistor
(c) pure resistor
(d) combination of an inductor and a capacitor

Answer 1

Answer:

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