Question

describe the construction and working of an electric bell with the help of a diagram

Answer 1

construction of an electric bell and electric bill consists of an iron core on which is found a wire as a coil one end of the call is connected to one terminal of battery and the other into a steel rod that acts like a spring for the hammer touching that screw contact The Other terminal of the battery is connected to the grave and contact with a switch in the middle working of an electric bell electric current flows through the coil when the switch is on and the iron core acts as an electromagnet iron iron core attracts the Hammond hits the bell and produces a sound the circuit breaks at the screw contact when the hammer moves towards the iron core this point the iron Core cases to be an Electromagnet the hammer is pulled back to its original position due to the spring action of the Steel rod and then touches the contact again to completed and current flows through the coil again Aai the hammer stripes the bill again the process repeats itself and you hear a ringing sound since the hammer keeps eating the bell until the switch is released

Answer 2

The construction of an electric bell consists of a gong, an electromagnet, a soft iron rod and a contact screw. The working of an electric bell: When the current passes through the electromagnet, it becomes magnetized which helps to attract the armature and after this the hammer raids and attract the armeture.
An electric bell is a mechanical bell that functions by means of an electromagnet.
Working :-
When an electric current is applied, it produces a repetitive buzzing or clanging sound. When an electric current flows through the coils, the rods became magnetic and attract a piece of iron attached to a clapper.
