- An emf is an electrical potential difference between two points.
- It is measured in volts (V).
- It is generated by a source such as a battery, generator, or transformer.
- An emf has the ability to drive current through a circuit.
- An emf can be either positive or negative depending on the direction of the current.
- The emf is independent of the resistance of the circuit.
- The magnitude of the emf is determined by the source and not the load.
- An emf can be induced by a change in magnetic flux.
