The impedance of a sereis `RL` circuit is same as the series `RC` circuit when connected to the same `AC` source separately keeping the same resistance. The frequency of the source is

Series RC and RL circuit

Draw phasor diagram for a RLC series circuit connected to ac voltage source.

If an LCR series circuit is connected to an ac source, then at resonance the voltage across

In a series L, R, C, circuit which is connected to a.c. source. When resonance is obtained then net impedance Z will be

In a series L, R, C, circuit which is connected to a.c. source. When resonance is obtained then net impedance Z will be

The given circuit diagram shows a series LCR circuit connected to a variable frequency 230 V source. Determine the source frequency which drives the circuit in resonance.

The power factor of an L-R series circuit is 0.5 and that of a C-R series circuit is 0.2. If the elements (L, C and R) of the two circuit are joined in series and connected to the same ac source, the power factor of this circuit is found to be 1. The ratio of the resistance in the L-R circuit to the resistance in the C-R circuit is
