User: what is the function of a circuit breaker
Weegy: A circuit breaker is like a fuse. They both do the same thing: the difference is that a fuse works once and has to be discarded if it blows once.
The basic idea is that if you have too many appliances on a circuit, [ a fuse will get so hot that the "wire" inside it will melt and ...
no current flow. Everything shuts down.
A circuit breaker will do exactly the same thing. A switch is connected to a bar which is quite close to an electromagnet. When there is too much current, the bar will move down which will do two things: it will flip the switch and it will move another bar down so that that bar is no longer in contact with another piece of metal which completes the path of the current.
Result: when the second bar moves from the first, the effect is the same as if a fuse was in the circuit. The difference is you can reset the circuit breaker. It is reusable. All you have to do is remove the offending appliance and reset the breaker. ]
