I have always been wondering . . . . does the insulation coating of a conducting wire have anything to do with its current conducting capacity ? I mean does the plastic insulation coating on the top affect the resistance of the wire or something?

Structures as simple as an ohmic contact ( the electrical interface between a semiconductor device and a conducting wire ) and as complicated as HFETs / HEMTs, RTDs, several types of laser diode, etc; all are designed to use quantum tunneling in their primary operation.

For a perfectly heat conducting wire or rod passing through a thermally resistive disk, and in perfect contact with the disk, the thermal resistance from wire to disk perimeter is also given by a standard formula : R = R Ln ( Rd / Rw ) / ( 2 Pi T )-See fig 2 in the attached file.

Its disadvantages include the potential for the entire fence to be disabled due to a break in the conducting wire, shorting out if the conducting wire contacts any non-electrified component that may make up the rest of the fence, power failure, or forced disconnection due to the risk of fires starting by dry vegetation touching an electrified wire.

Even if you have a unique solution for the voltages, you may not have a unique solution for the current, as any zero-resistance loop in the circuit ( such as two super-conducting wires running in parallel between the same two points ) can support an arbitrary circulating current .-- talk ) 02 : 02, 31 October 2013 ( UTC)

The commonly used nichrome for instance, at 32 AWG has a resistance of about 30 ohm / metre and constantan is about half that . 100 kohm / m is more like a poor insulator than a conducting wire, the sort of conductivity one gets from conductive plastic ( why is that a redlink ? someone write an article please ) .

Thus, for a typical inductance ( a coil of conducting wire ), the flux linkage is equivalent to magnetic flux, which is the total magnetic field passing through the surface ( i . e ., normal to that surface ) formed by a closed conducting loop coil, and is determined by the number of turns in the coil and the magnetic field; i . e .,
