2.4.72 - Core Practical 7 - electrical resistivity

CORE PRACTICAL 7: Determine the electrical resistivity of a material.

Use - core practical 7 - electrical resistivity to connect the rule to the data and decision in the question.

This matters because - core practical 7 - electrical resistivity determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - core practical 7 - electrical resistivity to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Core Practical 7 - electrical resistivity is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
