Electricity and circuits

Current transfers energy around circuits. Circuit components have various properties that can be measured and then used to make circuits for control and also circuits for testing other components.

This interactive is suitable for GCSE physics students studying electrical circuit symbols, electrical charge and current, potential difference, resistance and voltage graphs.

This interactive quiz is suitable for GCSE physics students studying series and parallel circuits, resistor networks and energy and power in electric circuits.

Electricity can flow either as direct or alternating current, and is used in homes to power electrical appliances. The National Grid distributes electricity throughout the country.

Understanding how to approach exam questions helps boost exam performance. Questions will include multiple choice, descriptions and explanations, using mathematical skills and extended writing.
