Keeping the source frequency equal to the resonating frequency of the series LCR circuit , if the three elements L,C and R , an 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 branch of the circuit for the elements and source whose values are $L= 5.0 \;H,C= 80\;\mu F, R= 40 \Omega$ for this frequency
