electrical current
Charge in motion
Electrical current is the flow of electric charge through a conductor, measured in amperes.
Current moves through wires like water through pipes—the analogy extends to voltage (pressure) and resistance (pipe diameter).
The electrical current in your house runs at about 15 amps.
Direct current (DC) flows one direction; alternating current (AC) reverses periodically.
