key term - Electric potential difference

Definition

Electric potential difference refers to the difference in electric potential energy per unit charge between two points in an electric field. It represents the work done per unit charge to move a positive test charge from one point to another.

Voltage:

Voltage is another term for electric potential difference. It measures how much electrical energy is transferred per unit charge.

Current:

Current refers to the flow of electric charges in a circuit. It is directly related to electric potential difference and inversely related to resistance.

Resistance:

Resistance is a measure of how difficult it is for current to flow through a material or component. It affects the amount of voltage needed for a given current.
