Answer:

Just consider the resistance as water flowing through a pipe. If the pipe is too small in radius (consider thin wire as small pipe) water can’t flow easly. If the pipe is big in radius (consider thick wire as big pipe) water can flow easly. So flowing water through a small pipe for a long distance will inversly affect the normal flow where as flowing water through a big pipe for a small distance will not affect too much the normal flow.

So long & thin wire has high resistance. Short & thick wire has low resistance.

B. A wire that is 2 m long and has a cross-sectional area of 0.066
