Electricity

Part of Physics

  • Electricity

    • Generation of electricity

      Electricity can be generated using a turbine to drive a generator before distribution. Renewable and non-renewable energy sources have pros and cons in of cost, reliability and pollution.

    • Electrical power

      Power is a measure of how quickly energy is transferred. Efficiency is a measure of how much useful energy or power is transferred. By considering where energy is ‘wasted’ we can improve efficiency.

    • Electromagnetism

      Magnetism can cause forces to act without any . By understanding how permanent magnets and electromagnets work, we can describe and explain their uses in the world around us.

    • Charge and current

      Current is a flow of electrical charge. Voltage measures the energy carried by the charge flowing in a circuit. This electrical energy is transferred in the circuit into light, heat and movement.

    • Series and parallel circuits

      Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values.

    • Applications of series and parallel circuits

      By considering how we control our appliances in our homes, we can understand how switches and variable resistors should be included in electrical circuits.
