For an LCR circuit,

In an LCR circuit .

For an LCR circuit, the power transferred from the driving source to the driven oscillator is P = I^(2) Z cos phi .

In a series LCR circuit

Keeping the source of frequency equal to the resonating frequency of the series LCR circuit, if the three elements L, C and R in are arranged in parallel , show that the total current in the parallel LCR circuit is a minimum at this frequency. Obtain the r.m.s. value of current in each brach of the circuit for the elements and source specified in for this frequency.

In series resonace, LCR circuit, below the resonant frequency, the circuit is

In LCR circuit as shown in figure
