1. A coil of resistance 50 2 and inductance of 100 mH is connected in series with a capacitance of 500 µF to a 200V 50HZ supply. Find the total impedance, current through the circuit, and voltage across each element. Hence, draw a vector diagram with current as the reference vector. 2. A coil with resistance 5 2 and inductance 100 mH is connected across a 100 V, 50 Hz supply. (a) Calculate the impedance of the coil. (b) Calculate the current through the coil. (c) Draw a vector diagram with voltage as reference vector. (d) Calculate VR and VL. 3. Three impedance of 3-j42 are connected in delta across a 400V,50HZ 30 AC supply. Find all the phase currents and line currents. 4. Three impedance of R= 102 and L=5mH are connected in STAR across a 500V,50HZ 30 AC supply. Find all the phase currents and line currents and power absorbed.
