Question

What causes an electric current to flow through a wire?
GPT 3.5
An electric current flows through a wire when there is a difference in electric potential between two points in the wire. This potential difference, also known as voltage, creates an electric field that pushes charged particles (usually electrons) through the wire. The flow of these charged particles constitutes an electric current. Additionally, the presence of a closed circuit, which provides a path for the current to flow, is necessary for the flow of electricity in the wire.
