The first telephone was made with the knowledge that sound gave off waves due to vibrations, like the ripples in water. These sound waves were copied over onto carbon grains, …which an electric current traveled through to make the grains vibrate. However, the different patterns of the grains altered the resistance of the grains against the electric flow. In this way the sound made more or less current flow in the circuit. These currents were in proportion to the sound waves that first entered. At the other end was a coil of wire within a magnet attached to a diaphragm. The variations in current caused the wire to move in the magnetic field. These vibrations move air, and that reproduced the sound at the other end! Answer Telephone is use to talk live to a person in far distances.
