Explanation:
Electrical energy consumed by an electrical appliance depends on two factors such as -
a. The power rating of the appliance.
b. The time period for which the appliance is used.
The electrical energy is thus measured by the formula - E= PT
An appliance may run for a long time and may consume more electric energy. Since, it is consumed by more power and rating of the appliance, thus it is always high.
