For an LCR circuit, the power transferred from the driving
Question:

 For an LCR circuit, the power transferred from the driving source to the driven oscillator is P = I2Z cos φ.

(a) Here, the power factor cos 0, 0. φ ≥ ≥ P

(b) The driving force can give no energy to the oscillator (P = 0) in some cases.

(c) The driving force cannot syphon out (P < 0) the energy out of oscillator.

(d) The driving force can take away energy out of the oscillator.

Solution:

(a) Here, the power factor cos 0, 0. φ ≥ ≥ P

(b) The driving force can give no energy to the oscillator (P = 0) in some cases.

(c) The driving force cannot syphon out (P < 0) the energy out of oscillator.
