Why we specifically note resistance in a circuit while all part of a wire have some resistance..???
The resistance of the rest of the circuit compared to the resistance of the resistor is negligible.

A 10m length of aluminium wire has a diameter of 1.5mm. It carries a current of 12A. Find (i) the current density. (ii) the drift velocity (iii) the electric field in the wire. aluminium has approximately 10^29 free electrons per m^3
You are given two nichrome wire of same length and different thickness Which wire will get heated first Give reason.? Asked Merlin Mary Mathew Answer: If the wires are connected one by one to a source, (or connected in parallel to the same source) the one having less resistance (Greater thickness) will get heated up first.
