Resistance vs resistivity

Resistance vs resistivity

Resistance tells you how much a particular component opposes current. Resistivity ρ\rhoρ tells you how strongly the material itself resists current, so it lets you compare materials fairly at the same temperature.

Step-by-step lessons on OCR A A Level Physics Resistivity. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
