Measuring current and potential difference You can measure current and potential difference in circuits. They are different things and so are measured in different ways.

Learn how electric circuits work and how to measure current and potential difference with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

The measurement of the electric current in an electric circuit therefore, depends on two factors primarily i.e. Potential Difference across the ends of the conductor and Resistance of the conductor.

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.
