Physics · Class 12 · CBSE — Alternating Current
For an LCR circuit, the power transferred from the driving source to the driven oscillator is \(P = I^2 Z \cos \phi\). Then
- the power factor cos f ≥ 0, P ≥ 0.
- the driving force can give no energy to the oscillator (P = 0) in some cases.
- the driving force cannot syphon out (P < 0) the energy out of oscillator.
- all of these.
Answer
(D) all of these.
