Resistance _ GCSE Physics
An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The length...

Transformers and the National Grid _ GCSE Physics
Electricity is transferred from power stations to consumers through the wires and cables of the National Grid. When a current flows through a wire some energy is lost as heat. The higher the current, the more heat is lost. To reduce...

Why outlets spark when unplugging - EMF & Inductors
When we cut the electricity to an inductor, we get a sudden intense spark across the switch. This is known as inductive kickback or a back EMF and is produced because of Faraday’s Law of Induction. Not mean to be tried at home! The...
