Charge and electric field strength

Electric charge comes in two types, positive and negative, and is measured in coulombs, C\text{C}C. Like charges repel and unlike charges attract, so electric forces can act without contact.

Step-by-step lessons on Edexcel A Level Physics Electric fields and Coulomb's law. 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.
