Thickness Length

Thickness and Length:

If you have a circuit with a short wire then the light will be brighter than if it was longer.
If you have a circuit with a fat wire then the light will be brighter than if it were thinner. The way the width works is; imagine the wire is a pipe and the electrons are water, more water can fit in a thicker pipe than a thinner one. The way the length works is; imagine the wire is a running track and the runners are electrons, it takes longer to run round a longer track.
