4. 11.2 Electric charge11.2 Electric charge
4. Describe an electric field as a region in which an
electric charge experiences a force.
5. Distinguish between electrical conductors and
insulators and give typical examples.
5. 11.3 Current & potential11.3 Current & potential
differencedifference
1. State that current is related to the flow of
charge.
2. State that the current in metals is due to a
flow of electrons.
3. Use the term potential difference (p.d.) to
describe what drives the current between two
points in a circuit.
6. 11.4 Resistance11.4 Resistance
1. State that resistance = p.d. / current and
understand qualitatively how changes in p.d. or
resistance affect current.
