How does a fuse work GCSE.

. A circuit breaker is an automatic switch that cut off current in a circuit when the current become too large. Insulation earthing fuses and circuit breakers help to protect us from electrical injury. Try to push more current through a circuit than its.

This uses an electromagnet. How does a circuit breaker work electromagnet GCSE. The M CB s disconnect the supply if too large a current flows.

Electrical energy is current multiplied by voltage and time. The two magnetic fields do not cancel each other out and the iron pivot is attracted to the live wire breaking the circuit. Circuit-breakers offer the following advantages compared to fuses.

The fuse which contains a piece of wire that melts easily if the current going through it is too great breaks the circuit if a fault in an appliance. The circuit breaker the wire and even the wire insulation are all designed to work as a systemand that system has limits. Inside each circuit breaker is a spring hooked over a small piece of solder a melt-able fusible alloy.

If the current exceeds the rating of the circuit-breaker the pulling force of the electro-magnet attracts an iron. How does a circuit breaker work GCSE electromagnet. This tutorial explains how a residual current circuit breaker works and its advantages compared to traditional fusesSubscribe for more physics tutorials.

Electromagnet is not strong enough to separate the contacts. The picture below shows a simple circuit breaker. Residual Current Circuit Breakers have the advantage of being highly.

Electricity can be hazardous.
