Resistance and the resistance equation

Resistance and the resistance equation

Resistance is the opposition a component provides to the flow of charge. In a metal, drifting electrons collide with vibrating positive ions, transferring energy and slowing their movement.

10.2 Resistance Lesson

  1. GCSE
  2. /Physics
  3. /10.2 Resistance

Step-by-step lessons on Edexcel GCSE Physics 10.2 Resistance, covering 10.2.1 Current in a circuit and conservation at junctions, 10.2.2 Resistance and variable resistors, 10.2.3 Series and parallel resistance, 10.2.4 I–V characteristics of components, and 10.2.5 LDRs and thermistors. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
