Answer:
electric resistance means the opposition to the electric current...
resistance of a conductor is affected by the length nd cross section of the conductor..
......,.....by length.........
resistance is directly proportional to the length.... means if length is more then resistance would also be more nd if length is less then resistance would also be less......
........... by area of its cross section........
resistance is inversely proportional to the area of the cross section of a conductor..... which means that if area is more then resistance is less nd if area is less then resistance is more....
