If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected? If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected? The voltage is doubled. The voltage remains constant. The voltage is quadrupled. The voltage is reduced by a factor of 4. The voltage is reduced by a factor of 2.
