MHT CET · Physics · Alternating Current
Average power in the \(L-C-R\) circuit depends upon
- A current
- B phase difference only
- C emf
- D current, emf and phase difference
Answer & Solution
Correct Answer
(D) current, emf and phase difference
Step-by-step Solution
Detailed explanation
The average power of \(L-C-R\) circuit
\(
P_{\text {av }}=V_{\text {rms }} \cdot i_{\mathrm{rms}} \cos \phi
\)
Hence, the average power depends upon current, emf and phase difference.
\(
P_{\text {av }}=V_{\text {rms }} \cdot i_{\mathrm{rms}} \cos \phi
\)
Hence, the average power depends upon current, emf and phase difference.
