What is the use of the spring in an electric bell?

The spring in an electric bell helps to return the hammer to its original position after striking the bell. This allows the hammer to strike the bell repeatedly when the circuit is activated. The spring's elasticity is essential for the bell to produce a ringing sound continuously.


Which form of energy is produced when a bell rings?

Sound energy is produced when a bell rings. When the bell is struck, it vibrates and creates sound waves that travel through the air. This sound energy is what we hear as the ringing of the bell.

Explain how an electric bell works?

When the bell is pressed the contact screw comes in contact with the iron strip and the circuit is complete . The current starts flowing through the coil. The electromagnet gets magnetised ant the soft iron armature gets attracted towards the electromagnet. The movement of the hammer causes the hammer to hit the gong. This movement beaks the circuit so that the current stops flowing and switches of the electromagnet. The spring pulls the armature back to it's original position , the circuit is remade and the process starts over again .This is how the bell rings.


Why in an electric bell the electric current stops again and again?

In an electric bell, the circuit is designed in a way that the current is periodically interrupted by the vibration of the bell's hammer against the gong. When the current flows, it creates a magnetic field that attracts the hammer, causing it to strike the bell and make a sound. Once the hammer strikes the bell, the circuit is broken, and the hammer springs back, only to repeat the process when the circuit is connected again.
