Electromotive Force
Definition
Electromotive force (EMF) refers to the potential difference between two points in a circuit. It's essentially what drives electric current around a circuit.
Analogy
EMF is like the water pressure in your garden hose. The higher the pressure, the more water flows through the hose. Similarly, a higher EMF results in a greater current flow.
Related terms
Voltage: This is another term for potential difference or electromotive force. It's measured in volts.
Resistance: In electrical circuits, resistance is a measure of how much an object resists the passage of electric current.
Ohm's Law: This law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points.
