In an electric circuit, what role does a battery typically serve?

A battery serves as a power source in an electric circuit. This means that it provides the necessary electrical energy to drive current through the circuit. When a battery is connected in a circuit, it generates a potential difference (voltage) that causes electrons to flow, allowing various components of the circuit to function.

The energy stored in the battery, usually in chemical form, is converted into electrical energy when the battery is connected in a circuit. This is crucial for powering devices and components such as lights, motors, and other electrical loads that require energy to operate.

Additionally, understanding the distinction between a battery's function and other components in a circuit enhances the comprehension of electrical systems. Conductors are materials that allow current to pass through easily, loads consume electrical energy (like light bulbs or appliances), and resistors limit current flow. The battery specifically stands out as a source of energy in this context, making option C the correct choice.
