How does a circuit breaker work gcse physics

WebA circuit breaker is defined as, switching device which interrupts the faulty current and performs the function of a switch thus protecting the electrical system from damage. … Webbreaks the circuit and disconnects the appliance. For example, if the fuse rating is 3 amps, then a current greater than 3 amps will blow the fuse. We must look at the heating effect of current to understand how a fuse works in more detail. Which Fuse is Correct for an Appliance? If we know the voltage and the power of an appliance
