why is a telephone wire in the form of a spring..?

Answer 1

A short history lesson. When phones first came out there were no wireless telephones. So if you wanted to talk on the phone while fixing dinner, you had to have a long cord. When the cords were straight (not in the form of a spring), they got all tangled up and made a wad of cord around the phone. In order to resolve this problem, they found that coiling the wire they were able to give people the ability to get more than a foot or two from the phone and not get the wire so tangled up as well as end the unsightly mess of wire around the phone.

Answer 2

so that sound can travel in a consistent pattern, making the wires inside it protected, stretched and more convenient for its shape can be extented not like straight wires, it occupies a lot of space, when its in curled, it occupies less but can be maxmized in length.

Answer 3

Crazy you ask I just bought a straght cord from the 99 cents store I've never seen one before.

Answer 4

because it meant to be elasticated and has memory so when you stretch it it should coil back correctly .. also stops them tangling but after heavy usage they will tangle and be a pain simply replace lead not phone !!...

Answer 5

better stretching capabilites and looks smart than a thick wire...

Answer 6

it acts as a shock absorber so when you inevitably stretch the cord out it won't break as easily.

Answer 7

1. space ki problem.... everything shrinking
2. better visibility....adangi na lage

Answer 8

so that you can stratch it to maximum.i.e. where you are sitting.
