The maximum power is dissipated for an ac in a/an: (a) resistive circuit (b) LC circuit (c) inductive circuit (d) capacitive circuit

Answer: (a). P = VrmsIrmscos φ is maximum when cos φ = 1, i.e. φ = 0. In a purely resistive circuit φ = 0; in L, C or LC circuits φ = 90° and P = 0. So the answer is (a) resistive circuit.

Power, Power Factor & Wattless Current

The maximum power is dissipated for an ac in a/an:

Show answer and solution

Answer: (a)

$P = V_{rms}I_{rms}\cos\phi$ is maximum when $\cos\phi = 1$ , i.e. $\phi = 0$ .
In a purely resistive circuit $\phi = 0$ ; in L, C or LC circuits $\phi = 90^\circ$ and $P = 0$ .
So the answer is (a) resistive circuit.
