TOPIC: Fundamentals of Alternating Current Powers Give illustration and a step by step solution. Final answer must be in 4 decimal places. 1. A load takes 55kW at 70% power factor lagging from a 240V, 50Hz supply. If the supply is made 60Hz, with the voltage remaining the same, what will be the kW load at 60Hz? 2. An inductive coil takes a current of 2A and consumes 160W when connected to a 240V supply. A second coil when connected across the same supply takes 3A and 500W. Find the total power when the two coils are connected in series to the supply. 3. A series RC circuit is connected to 230V, 60Hz source. If the power taken by the circuit is 4,800W and the voltage drop across the resistor is 115V, calculate the capacitance of the capacitor. Thank You in advance!
