Question
hen a dc𝑑𝑐 voltage of 100 V100 V is applied to an inductor, a dc𝑑𝑐 current of 5 A5 A flows through it. When an ac voltage of 200 V200 V peak value is connected to inductor, its inductive reactance is found to be 20√3Ω203Ω. The power dissipated in the circuit is _______ W.JEE Main 2024 (06 Apr Shift 1)
Solution
The power dissipated in a purely inductive AC circuit is zero. This is because the voltage and current are out of phase by 90 degrees, resulting in a power factor of zero. Therefore, regardless of the values given in the problem, the power dissipated in the circuit is 0 W.
