Study Notes
Current Flow Between Different Potentials
- When two objects with different electrical potentials are connected by a wire, electrons flow from the higher potential to the lower potential.
- This flow continues until the potentials equalize, and the current stops.
- A potential difference is needed for current to flow through a conductor.
Electromotive Force (EMF)
- EMF is the electric potential created by an electrochemical cell or a changing magnetic field.
Voltage
- Voltage is the electric potential difference between two points.
