4.4.99 - Field lines and equipotentials

Draw and interpret field-line and equipotential diagrams for radial and uniform electric fields.

Use - field lines and equipotentials to connect the rule to the data and decision in the question.

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

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

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