Vedclass · Answer

(C) In a series $LCR$ circuit,the total alternating emf $(V)$ is given by the phasor sum of the individual voltages across the resistor $(V_R)$,inductor $(V_L)$,and capacitor $(V_C)$.The formula is:$V = \sqrt{V_R^2 + (V_L - V_C)^2}$Given values:$V_R = 80 \ V$$V_L = 40 \ V$$V_C = 100 \ V$Substituting these values into the formula:$V = \sqrt{(80)^2 + (40 - 100)^2}$$V = \sqrt{6400 + (-60)^2}$$V = \sqrt{6400 + 3600}$$V = \sqrt{10000}$$V = 100 \ V$Therefore,the value of the alternating emf is $100 \ V$.

The value of the alternating emf in the given series $LCR$ circuit is: (in $V$)
