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. 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.
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 …
