V=IR (voltage is equal to amperage multiplied by resistance)
1 = V/R (amperage is equal to voltage divided by resistance)
R = V/I (resistance is equal to voltage divided by resistance)
The resistance in a circuit is halved. What happens to the voltage (if the Amperage is
kept the same)? (1 point)
The voltage is increased by a factor of 4.
O The voltage remains the same.
O The voltage is doubled.
O The voltage is halved.
