What this covers
This standard sits within Electricity. In a one-to-one lesson we make sure the idea is clear first, then move straight to applying it in the exact way SPM asks, with correct units and full working.
Formulas you may need
How it is examined
It can appear in Paper 1 (objective) and Paper 2 (structured), and where an experiment applies, in Paper 3. We do not predict which questions appear; we prepare the technique for all of them.
A common mistake
How to study it
Learn the definition precisely, practise one or two SPM-style questions with full working, and link it to the rest of Electricity. If it keeps costing marks, a one-to-one lesson fixes exactly that.

What you need to know
Current and Potential Difference (standard 3.1) is part of Electricity in Form 5. Be able to define its key terms with the correct SI units and explain the idea in one precise sentence.
Relevant formula: Q = It, V = W / Q, recall it from memory (no formula sheet is given) and write units on every line.
How it is examined
In Paper 1 this appears as an objective question; in Paper 2 as a define, explain, describe or calculate item. Watch the command word: "define" wants one sentence, "explain" wants the physics reason, "calculate" wants formula, substitution with units, and the answer with its unit.
We never predict which questions will appear.
