Electricity

Electric Current Electric current is defined as the rate of flow of electric charge past a point in a circuit. Electric Current The rate of flow of charge: I =…

Potential Difference Potential difference (p.d.) between two points is defined as the energy transferred per unit charge passing between those points. Potential…

Resistance Resistance is defined as the ratio of the potential difference across a component to the current flowing through it. Resistance R = (V/I) where R =…
