Master Electrical Resistance and Ohm’s Law (GCSE Physics)

Electrical resistance explained clearly for GCSE Physics, GCSE Combined Science and IGCSE Physics students. Learn what resistance is, why it happens, and how to use Ohm’s Law (V=IR) to solve exam questions. In this lesson, you'll learn: • What electrical resistance is • Why resistance occurs in wires and components • The symbol and unit for resistance (ohms, Ω) • Ohm’s Law explained: V = IR • How to calculate resistance, current, and voltage • How resistance behaves in series circuits • How wire length and thickness affect resistance This is essential knowledge for GCSE Physics, IGCSE Physics, Combined Science, and equivalent international courses.
