electrical signal
Current carrying information
An electrical signal is a voltage or current that varies over time to convey information.
Electrical signals carry data through wires, circuits, and electronic systems—from the impulses in a telephone line to the binary patterns in a computer.
The term also applies to the nerve impulses that transmit information through biological systems: The brain sends electrical signals to the muscles.
