When a voltage of 100V at 50Hz is applied to a choking a coil A, the current taken is 8A and the power is 120W, when applied to a coil B, the current is 10A and the power is 120W. what power will be is 10A and the power is 120W. what power will be taken when 100V is applied to the two coils connected in series?
leaving a freevway. Current from the opposite side must travel further, weakening the potential on that side. This creates a potent the motor in that direction, causing the motor to spin. O Only the side where the switch is closed forms a cormplete circuit, so the motor must spin in that direction.
