Explanation:
Resistance is similar to friction for electrical energy; resistance causes the electrical energy to be lost as heat (thermal energy), just like friction causes mechanical energy to be lost as heat. Resistance is a measure of how much voltage an electrical element needs in order to increase the electric current.
