Answer Posted / krishna r
if there any short occur, the heavy current will pass
through in that top point. its size is large because it
should be low resistance, according to resistivity = RA/L,
ie, Area is inversely proportional to resistance. so if area
increases , resistance decreases.......... please reply if
you find answer wrong .....
