Charge, current and complete circuits

Charge, current and complete circuits

Electric charge is carried through a metal circuit by delocalised electrons. Charge is measured in coulombs, with symbol QQQ and unit C\text{C}C.

10.1 Circuits, charge and current Lesson

  1. GCSE
  2. /Physics
  3. /10.1 Circuits, charge and current

Step-by-step lessons on Edexcel GCSE Physics 10.1 Circuits, charge and current, covering 10.1.1 Structure of the atom, 10.1.2 Circuit diagrams and symbols, 10.1.3 Series and parallel circuits, 10.1.4 Potential difference and voltmeters, 10.1.5 Energy transferred, charge and potential difference, and 10.1.6 Current, ammeters and charge flow. 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.
