Electrical circuits

Part of Combined Science

  • Electrical circuits

    • Conductors and insulators - CCEA

      What is electric current and how is it caused by moving electric charges? What are the effects of charge and electric fields on conductors and insulators?

    • Simple circuits and Ohm’s law - CCEA

      Learn about simple electric circuits, the symbols used to show their different components and how to carry out an investigation into Ohm's law.

    • Resistance - CCEA

      Learn how to calculate resistance in an electrical circuit and how resistance depends on the length of conductor.

    • Household electricity

      Learn about how electricity is used in homes and how this power is converted into other forms of energy and measured.

    • Protection from electric shock

      Learn about how we can protect ourselves from electric shock.
