The electromotive force of a standard cell is measured with a potentiometer that gives reading of 1 3562 V When a 1 MQ resistor is connected across the standard cell terminals the potentiometer reading drops to 1 3560 V What is the internal resistance of the standard cell A 120 V DC motor draws a current of 100 A and is located 1000 ft from the supply source If the diameter of the copper transmission line is 0 45 inch what must be the voltage of the supply
