Will current usage increase with different length of wire?
Given all other factors are same, with only the wire length increased (for example, 0.5 meter increase to 50 meters,) will the current consumption/usage increase as well?


Generally there are two types of load to consider.

Dumb loads

This includes things like lightbulbs, heaters and motors whose current draw varies with voltage. As the voltage drops the current will fall too. Adding extra cable will cause a voltage drop at the load so the current drawn will fall.

Smart loads

This includes things like computer / TV power supplies, motor speed controllers, LED lighting PSUs, etc. These differ in that they regulate the output they provide and when the voltage decreases they increase the current draw from the mains to provide the required output power. Adding extra cable will cause a voltage drop at the load so the current drawn will increase.
