What Is Electrical Energy
The flow of electric charge is defined as electrical energy. During dry season we often experience spark or crackle when we take off our cloths or sweaters. Lightening is another example of the electric charge. These phenomena are mostly due to the discharge of electrical energy stored in our body due to rubbing of insulating surface. The electric energy is defined by different terminologies such as charge, current and potential. The humans have developed the methods of storing this electrical energy and using it for later use. The electrical energy can be produced by many means like burning of fossil fuels, heat of the nuclear reactions which in turn is used to produce steam which powers a generator. This generator thus produces electricity. The electrical energy is also developed using kinetic energy from wind and water which in turn is used to power such generators to produce electricity. These require a transformer which converts electrical energy into higher voltage with lower current. The electrical energy is stored in capacitors and batteries.
How Is Electric Energy Produced?
The sub atomic particles interact with the electromagnetic force to produce electrical energy. The electron and protons within an atom create charge which in turn can be transferred between two bodies using a conductive wire. The energy which flows in the conductive wire is called as current and it refers to the movement of the charge. There are two types of current, the direct current is one in which the electricity flows in just one direction while alternating current is the one in which electricity flows in either directions and is used in large power requiring places such as residences.
The range and power of the electrical energy depends on its potential. The electric charge in an object exerts a force through its electrical field. This force exerts the object towards or away from the charge, which is also dependent on their electromagnetic polarization. It is seen that the positively charged electricity pushes an object away whereas negatively charged electricity pulls the object towards it.
The oldest record of the understanding of electricity was by ancient Egyptians. However, till 1600 the knowledge of electricity was only intellectual. Many scientists kept on studying electrical energy and by 1800 scientists such as Alessandro Volta identified ways by which electrical energy can be harnessed in the form of battery. The research on electricity was carried forward by Thomas Edison and Nikola Tesla. The studies and research by these forerunners are now being taken forward by the engineers and physicists of today and much is known and a lot remains to be discovered about electrical energy.
Electrical energy is defined as the flow of charge and is produced by the interaction of the electromagnetic force with the sub atomic particles. The electrical energy is converted into electricity which is of immense use. The electrical energy can be produced by air, water and by the burning of fossil fuels. The energy from these sources is passed to generators where electrical energy is produced using a trandformer.
