B4. Figure B4.1 shows the an ideal transformer, with an A.C. supply of 120V 220° at its primary side. The turn ratio of the primary side to secondary side is 5: 1. On the secondary side, a load consisting of a 202 resistor and a 602 inductor connected in series. (b) 120220°V Vp 1=5A248° Figure B4.1 48⁰ Calculate: (a) (i) the secondary voltage, (Vs); (ii) the secondary current (Is); (iii) the primary current (IP); and (iv) the power factor of the a.c. source if a capacitor of 452 is connected in parallel to the load. -42⁰ VA E=24V 20⁰ V=20VZ-42° Figure B4.2 Electrical Load ele (i) the total impedance (ZT) in polar form; (ii) the capacitor's impedance (Zc) in polar form; (iii) the power factor (FP) of the circuit; and (iv) the total power (PT) delivered. R 252 L 652 Figure B4.2 shows a phasor diagram of a capacitor connected in series to a resistor. The A.C. supply to the circuit is 24V 20⁰.
