) : Measured in using an ammeter connected in series. Resistance ( ) : Measured in Ohms ( Ωcap omega ) . Resistance increases if the wire is longer or thinner. 4. Practice Questions Hint/Formula
Now that we've covered the theory, it's time to put your knowledge to the test. These exercises are designed to cover all the key topics.
Before attempting exercises, ensure you understand:
When presented with a complex, messy circuit diagram, use your finger or a colored pencil to trace the path from the positive terminal of the battery to the negative terminal. This makes it instantly clear whether components are in series or parallel. f2 science electricity exercise top
