It means that the capacitive reactance and the inductive reactance are equal in magnitude but nullify the effect of each other, as they oppose each other. In this condition the impedance of the network would be equal to the resistance.

Description : In parallel RLC resonance circuit at resonance the current will be (1) Minimum (2) Maximum (3) Zero (4) Infinite

Answer : In parallel RLC resonance circuit at resonance the current will be Minimum

Description : Magnitude of current at resonance in R-L-C circuit?

Answer : The current will be maximum if it is a series rlc circuit.

Description : The power factor at resonance in R-L- C parallel circuit is?

Answer : since a rlc circuit at resonance behaves like a pure resistive circuit, i.e there is no phase difference between current and voltage, hence the power factor is unity.

Description : In a series RLC high Q circuit, the current peaks at a frequency (1) equal to the resonant frequency (2) greater than the resonant frequency (3) less than the resonant frequency (4) equal to half the resonant frequency

Answer : In a series RLC high Q circuit, the current peaks at a frequency equal to the resonant frequency
