Question

Examine the scenario. A circuit is arranged so that 20 A of current is flowing through it. The battery is replaced with another battery with ¼ the original voltage. Which choice correctly describes the effect on the current? The current reduces to ¼ of the original current because a smaller voltage indicates that there is less energy to move the charge. As voltage decreases in a circuit, current also decreases. The current decreases to ½ of the original amount because a smaller voltage indicates that the flow of charge is being restricted, but only by half. As voltage decreases, current will decrease also, but by a smaller amount. The current increases to 4 times the amount because a smaller voltage indicates that there is less to restrict the flow of charge. As voltage decreases in a circuit, current increases The current stays the same because a smaller voltage means there is less energy for each charge, but more charges are moving through the circuit. Current and voltage do not affect each other.

Answer 1

The current reduces to ¼ of the original current because a smaller voltage indicates that there is less energy to move the charge. As voltage decreases in a circuit, current also decreases.
