Class 12 NEET Physics Electromagnetic Induction and Alternating Currents 1

Concept:The average power dissipated in an AC circuit is given by the product of RMS voltage, RMS current, and the power factor ($\cos \phi$).Explanation:The formula for the average power ($P_{avg}$) dissipated in an AC circuit is:$$P_{avg} = V_{rms} I_{rms} \cos \phi$$Here, $V_{rms}$ and $I_{rms}$ are the RMS values of voltage and current, and $\phi$ is the phase angle between the voltage and current. Since the power dissipated is directly proportional to $\cos \phi$, it depends on the phase angle between $V$ and $I$.Answer:B. depends on phase angle between $V$ and $I$
