Internal Resistance
Electric Current
- When a switch is closed in a circuit, free electrons in the conductor experience an electric field which causes them to move in one direction.
- Electrons will flow from the negative terminal of a battery to the positive terminal.
- Energy is provided by a chemical reaction in the battery or by the mains power supply to allow the electron current to flow.
Electric Power
- P = IV
- Where I is the current through a component and V is the potential difference across a component.
