In a series L, R, C circuit which is connected to ac source, when resonance is obtained then net impedance Z will be:
In a series combination of R, L and C to an AC source at resonance, if R = 20 Ω, then impedance Z of the combination is
A pure resistance R, pure capacitance C and pure inductance L are connected in series and the impedance of the circuit at resonance is Zo. If they are connected in parallel to each other, the maximum impedance at resonance will be:
