Assertion: An inductance and a resistance are connected in series with an `AC` circuit. In this circuit the current and the potential difference across the resistance lag behind potential difference across the inductance by an angle `pi//2`.
Reason: In `LR` circuit voltage leads the current by phase angle which depends on the value of inductance and resistance both.

Options

A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Answer

B

Explanation

We can use a capacitor of suitable capacitance as a chok coil, because average power consumed per cycle in an ideal capacitor is zero. Therefore, like a choke coil, a condenser can reduce `AC` without power dissipation.
