What type of current is supplied by a battery?

A battery supplies direct current (DC). This type of current flows consistently in one direction, which is from the positive terminal to the negative terminal of the battery. In most applications, this characteristic of direct current makes it suitable for running devices like electronic appliances, toys, and cars, where the flow of electrons needs to be stable and unidirectional.

Alternating current (AC), in contrast, changes direction periodically and is typically used for powering homes and industries due to its efficiency over long distances. Regulated current refers to current that has been controlled to remain at a constant level, but this is not a characteristic of all battery supplies. Flux current is not a standard term in electrical theory related to current types.

The nature of direct current provided by batteries is essential for understanding many fundamental applications in electronics and electrical engineering, making it a key concept in physics studies.
