so say i have a nichrom wire of 0.5 mm dia, and pass 230 v through it.and i coil it up, but some part of the coil touched (imagine the wire parallel to each other so basically 2 circle.) will it short the circuit? i have been told that the area they touch is extremely smaller since they are circular, so the resistance is very high compare to going through the wire normally, hence it doesn't short?

It depends on your setup, the surface of the wires and some other things. As an example: if you contact two banana plugs, you can get a resistance below 0.1 Ohm, and their contact area is basically point-like.
