Show all your steps and draw diagrams where necessary. Addexplanatory notes where necessary.
A 25-O resistance is connected in series with a 30-mH inductanceand a 12-µF capacitor and are connected to a 90-V (rms) ac. If thefrequency of the ac source is 500 Hz, calculate
(i) the current in the circuit.
(ii) the voltage across each element
(iii) the phase angle f
(iv) the power dissipated in the circuit
