An inductive coil having a resistance of 15 Ω takes a current of 4 A when connected to a 100-V, 60 Hz supply. If the coil is connected to a 100 -V, 50 Hz supply, calculate (a) the current (b) the power (c) the power factor. Draw to scale the vector diagram for the 50-Hz conditions, showing the component voltages
