Atoms, charge and neutrality

Everything around us is made from atoms. Protons are positive, electrons are negative, and neutrons have no charge.

3.1 Static and charge Lesson

  1. GCSE
  2. /Physics
  3. /3.1 Static and charge

Step-by-step lessons on OCR GCSE Physics 3.1 Static and charge, covering 3.1.1 Positive and negative charge, 3.1.2 Static electricity and forces between charged objects, 3.1.3 Electron transfer and static electricity, 3.1.4 Electric fields, 3.1.5 Current as a flow of charge, 3.1.6 Current in a single closed loop, and 3.1.7 Charge, current and time. Each one builds up to exam-style questions. Paper 2 and Paper 4 include synoptic questions that draw on Topics P1–P4, so revisit earlier topics before final exams rather than treating each paper as self-contained.
