Q2-A coil, having a resistance of 15 N and an inductance of 0.75 H, is connected in series with a capacitor (Fig.1.a. The circuit draws maximum current, when a voltage of 200 V at 50 Hz is applied. A second capacitor is then connected in parallel to the circuit (Fig1. b). What should be its value, such that the combination acts like a non-inductive resistance, with the same voltage (200 V) at 100 Hz? Calculate also the current drawn by the two circuits. R L R L V = 200 V V = 200 V C2 fj = 50H2 fz = 100HZ %3!
