an inductor of 0.5H inductance and 90 ohms resistance is connected in parallel with a 20 microF capacitor.A voltage of 230v at 50 hz is maintained across the circuit. Determine the total power taken from the source
Xl 2pi fl 157 Ohms Z of L sqrt [(90^2) + (157^2)] 180.97 Ohms I of L I of R 230V/180.97 Ohm 1.27 Amps Total power taken from source (I^2)*(R) (!.27A^2)*(90 Ohm) 145 Watts
