In an electric circuit, electrons in the wire flow due to an electric potential difference, also known as voltage.

Here's a breakdown:

• Electric Potential Difference (Voltage): Voltage is the difference in electric potential energy between two points in a circuit. It's like the pressure that pushes the electrons along the wire.
• Electric Field: The voltage creates an electric field within the conductor, which exerts a force on the electrons, causing them to move.
• Electron Flow: Electrons move from an area of higher potential (negative terminal) to an area of lower potential (positive terminal). This flow of electrons is what constitutes electric current.
