A circuit is a path along which electric current flows. How would changing the battery in a circuit from 9 volts to 1.5 volts most likely affect the circuit?

With the same circuit resistance, lowering the battery voltage from 9 volts to 1.5 volts lowers the current, according to Ohm’s law. Since current is the rate at which electric charge flows, less charge would flow through the circuit. The resistance itself would not change just because the battery voltage changed, so the correct choice is “Less electric charge would flow in the circuit.”
