Answer:
Process of the working of an electric bell :-
Now that you have an understanding of the important parts in an electric bell, the step by step process of the working of the electric bell is described below:
- The switch is pressed and current flows through the circuit.
- The electromagnet is powered and generates a magnetic field that attracts the iron strip towards it.
- The striker strikes the gong (bell).
- When the striking arm strikes the gong, the contact is broken and current stops flowing through the circuit.
- This causes the electromagnet to lose its magnetic field.
- The connected spring arm returns the striker to its original rest position.
- The contact is restored and current flows through the circuit
- The process is repeated from the beginning.
Hope it helps !!!
