C.3.11—Testing laws with logarithmic plots

Use logarithmic plots to test exponential and power-law variations, including radioactive decay and capacitor charging or discharging.

Use c.3.11—testing laws with logarithmic plots to connect the rule to the data and decision in the question.

This matters because c.3.11—testing laws with logarithmic plots determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply c.3.11—testing laws with logarithmic plots to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: C.3.11—Testing laws with logarithmic plots is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
