We are in need of energy for our industrial, commercial and day-to-day activities, and we use energy in different forms. Out of all the forms of energy, electric energy is the most important one as it can be generated (actually converted from other forms of energy) efficiently, transmitted easily and utilized ultimately at a very reasonable cost.
