A **DC battery** is a type of battery that stores electrical energy in the form of direct current (DC). Direct current means that the electrical charge flows in one direction, as opposed to alternating current (AC), where the direction of the current changes periodically.
### Key features of a DC battery:
1. **Constant Voltage**: The voltage output of a DC battery remains constant over time, providing a steady flow of energy in one direction.
2. **Usage**: DC batteries are commonly used in portable devices like smartphones, flashlights, remote controls, and other gadgets that need a stable and constant power source.
3. **Example**: A typical example of a DC battery is the one you find in a flashlight or a car battery, where the battery delivers power in a steady, one-way current.
In short, a DC battery provides a constant and unidirectional flow of energy to power electronic devices.
