What is the power factor of a series RLC circuit under resonance condition?(a) 0(b) 1(c) Infinity(d) 100 |
|
Answer» Right choice is (b) 1 For explanation: The power factor for a series RLC circuit in resonance condition is always unity because the current is in phase with the voltage under resonance condition. Φ=0^0 => cos ϕ = 1 i.e. power factor = 1. |
