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.
How does insulated wire work in an electric bell?
Insulated wire means a conducting metallic wire will be covered by non conducting material such as nickel. As such a wire is wound on a soft iron core and as long as a current flows through such insulating wire then temporarily it comes a magnet and pulls the hand and it strikes the bell and sound is produced. By this time the circuit is broken and current stops flowing through the insulating wire and hence the core loses its magnetism and the hand is relieved and again it goes back to its original position and once again the circuit is completed and the cycle repeats and stroke produces bell sound. Hence insulating wire helps to produce magnetism temporarily.
Is an electric bell a permanent magnet?
An electo-magnet is used in an electric bell.
In electric bell electric energy is converted into which type of energy?
In electric bell, electrical energy is converted int sound energy.
Enlist any four effects of electric current on conductor with one example of each?
Effects of an Electric current -1) Heating effect -e.g. - Heater / Geyser etc.2) Magnetic effect -e.g. - Electric Bell etc.3) Chemical effect -e.g. - Battery charging etc.4) Lighting effect -e.g. - Electric bulb etc.
In an electric bell the electric current stops again and again?
The electric bell and the electric current stops over and over again because of the fluctuations in voltages.
If alternate current is pass trough electric bell will it ring?
if alternate current is pass through electric bell will it ring?
When a current flows through an electric bell what will happen to the armature?
When current passes through an electric bell, the armature gets magnetised and attracts the gong hence ringing the bell.
What should be the power of the battery you use in an electric bell?
depends on the size of the coil used in the bell Current Draw Of The Bell.
Do electric current cause coiled wire to become an electric bell?
No. A coiled wire can never become an electric bell without some more piecesand parts. When you have those, however, assembled in the right way, it's truethat passing an electric current through the coiled wire will cause the bell to ring.
Could a coiled wire become a bell with electric current?
yes
What happens to the armature and the hammer when the electric bell is switched on?
When power is applied to the armature coil, the armature which has the hammer attached to it is drawn into the coil. The bell is struck by the hammer. At the end of the hammer stroke there is a N.C. (normally closed) contact which is opened. The opening of the contacts stops the current flow to the armature coil and the armature and hammer return to the off bell position. In the off bell position the N.C. contact re closes and the cycle is repeated over again. This cycling will continue until the bell circuit is turned off.

What was the process of inventing the telephone?
Bell's interest in telephony sparked the idea of inventing the telephone. While working on a harmonic telegraph, a reed stuck on the transmitter that was converted to a continuous current. The sound heard on the receiver confirmed Bell's belief that sound could be transmitted and reconverted through an electric wire with the use of continuous electric current.
What is an electric bell used for?
it is like a door bell
