Current, resistance and potential difference
What you need to know
Describe how current depends on both the resistance of a component and the potential difference across it.
Calculate current, potential difference, or resistance using the equation:
V=IR
Use circuit diagrams to set up and check appropriate circuits to investigate factors affecting resistance, including the length of a wire and combinations of resistors.
