    Getting started with circuits

    Outcomes

    Before you get going be able to

    • Explain how electricity flows from high potential to low potential in a circuit.
    • Explain the difference between the flow of current (Amps) and the ability of electricity to do work (Volts).
    • Explain that resistance measures the ability of a charge to flow in a circuit.
    • Be able to construct a simple circuit on a breadboard.
    • Be able to find the value of a resistor from the codes on its body.
    You will find you will be able to identify various components on the way through.

    • Topic 2

      Simple electronics

      Electricity is a force measured in volts.

      Current is the amount of electricity that flows measured in Amps.

      Resistance is a force that opposes electrical flow and is measured in Ohms.

      Electricity needs to flow into a circuit.

            Measuring light intensity with multimeter

            In 2019, two of the four winners just lay their panels flat. Does the angle of the pane really matter?

            Experiment

            Connect your multimeter to your solar panel and investigate how to voltage fluctuates as the panel is moved about.

              The solar car is a circuit

              Electricity flows

              • out of the solar panel
              • through the switch
              • through the motor
              • back to the panel
