Hello.
Thinner the wire, more is power consumed.
The power consumed by the wire is nothing but heat loss took place in it.
The heat loss is given by; (I^2 )*R. Where R is resistance of wire element.
Now, R=(resistivity)*length/(area of cross-section) and I=V/R
The thinner a wire, the higher its electrical resistance. This is because the same number of electrons must squeeze through a smaller portal (the wire), and get in each others way in the process, thereby resisting the flow.
Think of a huge crowd of people trying to get down a narrow hall-way at a stadium. In the larger hallways, the crowd is moving just fine, but when they encounter the narrower hallway, they all try to squeeze in, but can't all fit at the same time, leading to resistance in the crowd's movement, so that the movement slows down at in the narrow hallway.
