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?
1 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.
2 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
3 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.
4 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.
