1.	For an LCR circuit, the power transferred from the driving source to the driven oscillator is `P = I^(2) Z cos phi`.A. Hence, the power factor `cosphi gt- 0, P gt-0`B. The driving force can give no energy to the oscillator (P=0) in some cases.C. the driving force cannot syphon out`(Plt0)` the energy out of oscialltorD. The driving force can take away energy out of the oscillator.
Answer» Correct Answer - A::B::C According to the question, power transferred, `P=I^(2)Zcosphi` Where I is the current, Z= impedance and `cosphi` is power factor. As power factor, `cosphi=R/Z` where, `Rgt0` and `Zgt0` `rArr cosphigt0 rArr Pgt0`
