Telephone:-It is an apparatus used for the transmission of speech or other sounds, with or without wires. It consists of a transmitter and a receiver generally connected by an electrical Conductor. The transmitter is usually a carbon microphone by means of which variable electrical impulse depending on the nature of the sounds made into the microphone are caused to flow through the circuit. In the receiver these impulses flow through a pair of coils wire wound upon soft iron pole process attached to the poles of a magnet. An iron diaphragm near the coils experiences variable pulls and thus vibrates so as to produce sounds corresponding to those made into the microphone.
