7. A coil, consisted of a variable indoctor Land a 0.812 internal resistance R (note that the variable inductor L is in series with the resistance R), is connected in parallel with a 3710*F capacitor to form a RC circuit. The circuit is then connected to a 220V, 350 Lt power source. Given that the circuit is having a resonant frequency of 350Hz, complete the followings (a) Sketch the circuit diagram: (6 marks) (b) Determine the inductance of the variable inductor : (5 marks) c) Determine the circuit impedance in resonant. Zo (2 marks) (d) Determine the supply current from the power source at resonant. 1 (2 marks) VHS00S Supplementary Exercise Page le) Determine the quality factor (2 marks) 16 State a method to improve the power factor of the circuit.
