There is a doubt regarding area of cross section... We know resistance z inversely proportional to area of cross section. But my ques z in greater area of cross sec. there are more no. of electrons comparetively so more collisons occur & less electric current flows & resistance should be high . Then how greater area of cross sec. can offer LOW resistance????
