How does a Phone Work?
The essential electro-mechanical functions that make a phone work are fairly simple and straightforward. This explanation describes the processes that make a land-line phone work. The processes that make cell phones work and that allow Voice over Internet Protocol (VoIP) telephones to work, are a bit more complicated, necessitating radio waves and Internet Protocol (IP). The basic principles to make any phone work, however, are the same. To make a landline phone work, two copper wires must transmit two things: signals and voice. The two wires, usually coated green and red, are the heart of the process that makes the phone work. While the telephone rests on the hook or in its cradle, a capacitor inside the phone cradle limits the amount of electrical current flowing to the ringer, actually a chip within a small speaker. The capacitor prevents a short circuit in the wires and the local telephone exchange equipment recognizes that the phone is hung up. For proper phone operation, sound mu
Well you plug your phone into the phone socket (or outlet diffrent countrys have diffrent names), then the phone socket it connected to the phone line, the phone line is connected to either a pole, or a green box at the end of the street, then from there its connected to the local exchange, then from the local exchange to the city exchange, then from there to the main exchange (unless your in the main city then your connected to the city exchange), then when you pick up the phone and dial a number if its a local number (e.g your mate down the street or around the corner), then your call will go through the local exchange and to their phone, if its someone say that lives in another city altogether like london, you phone their number, it will go throuhg your local exchange, then to the city exchange, then the main exchange, then to the local exchange of the person your phoning lives, if your ringing a mobile then the same goes local exchange > city exchange > main exchange > mobile excha
The telephone operates on simple principles. A telephone mouthpiece contains a thin metallic coating separated from an electrode by a thin barrier (today we use plastic) which connects to a wire carrying an electric current. When a person speaks into the mouthpiece, the acoustic vibrations from her speech push the metallic coating slightly closer to the electrode, resulting in variations in voltage and therefore a speedy conversion from acoustic to electric energy. The electric pulses are conveyed through a wire to the speaker on the other end, where electric pulses are converted into acoustic energy again. And the answer about cell phones above this one is not correct…. Cell phones do not work via satellite. (satellite phones do) Cell towers send/recieve a signal from your cell phone over the air, and the towers themselves are connected via landlines or circuits to the “cloud” of the phone system. The signal is sent digitally, but converted when entering the phone network back to an
Phones are hooked up to phone lines, which the lines are hooked up to wires which are directed through a big opereating machine that sends the phone call through wires to get to whomever you are trying to reach. Now cellphones are different because they are digital. The calls are transferred to a satellite that is then transferred to a disk that transfers your call to the cellphone that you are trying to contact. That;s the only way that I can explain it.
