2.4.76 - Variable-resistance potential dividers

Be able to analyse potential divider circuits where one resistance is variable including thermistors and light dependent resistors (LDRs).

Use - variable-resistance potential dividers to connect the rule to the data and decision in the question.

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

Example: apply - variable-resistance potential dividers to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Variable-resistance potential dividers is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
