Describe how current through a diode flows in one direction only.

Describe how current through a diode flows in one direction only.. Within Current, potential difference and resistance, this learning objective sits inside Resistors for AQA Physics 8463. Focus on using ideas such as diode accurately in your explanation. A strong response should define the core idea, describe the relevant physical process, and connect it back to the question wording instead of giving a vague definition. When revising, students should aim to explain the subject clearly, include precise physics vocabulary, and show how the idea links to the wider topic rather than listing isolated facts.
