WebThe electric circuit is completed by installing a push switch which you can press to generate sound in an electric bell. The switch also acts as the circuit breaker. So once the setup is completed, when the switch is pressed, the circuit loop is complete which causes the current to flow through the circuit. WebWhen the switch is pushed closed the circuit is completed and current flows through the electromagnetic coil. 1 . The iron striker is attracted to the electromagnet and strikes the bell. 2. As the striker moves towards the bell, the contact is broken . Electricity stops flowing through the coil which loses its magnetism. 3 .

WebWhat is a Circuit Breaker? Inside each circuit breaker is a spring hooked over a small piece of solder (a melt-able fusible alloy). Each breaker is connected to an electrical wire that runs through your house. The electricity that flows through your house runs through the solder. WebA circuit breaker is a switching device that interrupts the abnormal or fault current. It is a mechanical device that disturbs the flow of high magnitude (fault) current and in …

WebThe relay consists of two circuits. Circuit 1 is a simple electromagnet which requires only a small current. When the switch is closed, current flows and the iron rocker arm is attracted to the electromagnet. The arm rotates about the central pivot and pushes the contacts together . Circuit 2 is now switched on. http://www.gcsescience.com/pme8.htm
