The length of a conductor affects it resistance?

Question

The length of a conductor affects it resistance?

Answer 1

All other things being equal, the longer the conductor, the greater the resistance.  A piece of wire two meters long has twice the resistance of a piece of the same wire only one meter long.

Answer 2

yes.i had that problem before.an extention cord was so long the heater that was plugged into it wouldnt work.the thickness affects the resistance,and so does temperature.

Answer 3

Yes,

The resistance of the conductor is directly proportional to the length & inversly with the c/s area

Answer 4

Yes.

Longer = more resistance.

Answer 5

This can be confusing because it is easy to confuse resistance with resistivity.   The resistivity of the conductor does not change but, because there is more of it, the total resistance in the circuit increases.  So...  It also depends on voltage.  All else being equal, the higher the voltage (the lower the current), the less loss resistance (although it does not increase the resistivity of the conductor).  Hi tension power lines which carry electricity across the great distances have resistance (they are not superconductors) so the power company loses electricity just getting it from one place to another.  They don't like giving it away for free so they are interested in minimizing the losses as much as practical.   Therefore, they run the transmission lines at very high voltage.  Hope this helps.
