How does a circuit breaker work gcse physics
WebAC Residual current circuit breakers work by comparing: the current entering the appliance via the live wire with the current leaving the appliance through the neutral wire. The live wire and the neutral wire are wound around iron cores in opposite directions. http://passmyexams.co.uk/GCSE/physics/circuit-breakers.html

WebThis uses an electromagnet. If the current exceeds the rating of the circuit-breaker the pulling force of the electro-magnet attracts an iron latch which breaks the electrical contacts. Remeber to revise electromagnets - make sure you KNOW why the core should be made of a soft magnetic material! Webcircuit breakers work in a similar way to fuses, and also protect the circuit from damage if too much current flows but work in a different way. when circuit breakers detect a surge …
