| || ||You can think of resistance as being like a water pipe. A long, thin pipe makes it difficult for water to flow whereas a short, fat pipe makes it easy. The short, fat pipe has a smaller resistance and, for the same pressure, lets a bigger current flow through it. |
Here's another example: look at these decorator's tools in picture 2.2. The yellow one (on top) has a long thin nozzle; the orange one (underneath) has a short, wide nozzle. The decorator squeezes the handle to force out the filler (for filling cracks in the wall).
Imagine the decorator pushes with the same force on each of these, which one will have the bigger flow?
The orange one, because the big hole has a small resistance and it is easier for the gunge to flow through.
