Three 20 ohms non inductive resistors are connected in star across a three phase supply, the line current of which is 480 V. Three other equal non-inductive resistor are connected in delta across the same supply so as to take the same line current. What are the resistance values of these other resistors and what is the current flowing through each of them.
