2.4.64 - Electric current

Understand current as the rate of flow of charge and use I = ΔQ/Δt.

Use - electric current to connect the rule to the data and decision in the question.

This matters because - electric current determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - electric current to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Electric current is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
