L-R circuit

L.R. Circuit

In an electrical circuit R,L, C and a.c voltage source are all connected in series. When L is removed from the circuit , the phase difference between the voltage and current in the circuit is π/6. If instead ,C is removed from the circuit , the phase difference is again π/6 . The power factor of the circuit is

The phase difference between voltage and current in series L-C circuit is

Examples on L-R and L-C Circuits

In L-C-R series AC circuit,

In an electrical circuit R,L,C and an AC voltage source are all connected in series. When L is removed from the circuit, the phase difference between the voltage and the current in the circuit is pi//3 . If instead, C is removed from the circuit, difference the phase difference is again pi//3 . The factor of the circuit is
