Why will an electric drill operating on a very long extension cord not rotate as fast as one operated on a short cord?
To Explain: An electric drill having a very long extension cord does not rotate faster as compared to having a short cord.
Explanation of Solution
Introduction:
Resistance is a property of element which is introduced in a circuit or the material of the conducting wire. When current is passed through a conducting wire, it heats up.
The resistance of a wire depends on its length. A very long extension cord will have more resistance as compared to a short cord.
The resistance of the extension cord should be small so that it gets less heated up, so there is less loss of energy and more energy is available for the electric drill.
