For an L-C-R circuit, the power transferred from the driving source to the driven oscillator is P = I 2 c o s ϕ
a) Here, the power factor cosϕ > 0, P ≥ 0
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, then
