We explore resistors. First we look at why we might use a resistor in a circuit, then we look at what is meant by an ohmic conductor. This is critical stuff so expect to see it in your exam. This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.
