The battery’s role in charges is to?

• A. Increases potential energy of charges
• B. Keeps charge from gathering at the area of low potential
• C. Converts energy to light
• D. Stores energy as heat

Answer: (B)

A battery creates and maintains a voltage difference that drives current through a circuit. It does this by moving charges from the lower-potential side toward the higher-potential side, which prevents charges from piling up at a single low-potential location and keeps the current flowing. This continuous push is what overcomes resistance in the wires and loads, sustaining the circuit's operation. While charges may gain potential energy as they are moved inside the battery, the essential role is to maintain the voltage difference and drive ongoing charge movement. It’s not primarily about turning energy into light or storing energy as heat.
