A capacitor of reactance 4 3 and a resistor of resistance 4 are connected in series with an ac source of peak value 8 2 ~V . The power dissipation in the circuit is ________ W.

Step-by-step solution

aligned & Z = R ^2+ X ^2 ~L & Z = 4^2+(4 3 )^2 =8 & V _ rms = V 2 = 8 2 2 =(8 ~V ) & I _ rms = V _ rms Z = 8 8 =1 ~A aligned Power dissipated = I _ rms ^2 R =1 4=(4 ~W )
