Figure shows a series LCR circuit connected to a variable frequency 230 V source. L = 5.0 H, C = 80 muF , R= 40 Omega . Obtain the impedance of the circuit and the amplitude of current at the resonating frequency. :

In a series LCR-circuit, what is the potential drop across resistance at resonance, when the operating is 220V?

LCR circuit connected to a variable frequency 230 V source . L=5.0 H, C=80 micro F and R=40 ohm. Keeping the source frequency equal to the resonating frequency of the series LCR circuit, if the three elements, L, C and R are arranged in parallel, show that the total current in the parallel LCR circuit is minimum at this frequency. Obtain the current rms value in each branch of the circuit for the elements and source.
