Describe the concept of electric potential


One of the great unifying concepts of physics is that of energy. Earlier in our study we defined energy as that property of a system by virtue of which work may be done. There are numerous into electric energy. For example, a battery transforms chemical energy is transformed into some other form of energy. The electric motor, for instance converts electric energy into mechanical energy.

In electrical phenomena the concept that is of primary importance in all energy transfers is that known as potential difference. In our study of gravitational fields we discussed the concept of the potential that certain problems, such as those involving gravitational fields, could be much simplified by the use of energy considerations. The same will be found to be true for the electric field, which is so similar, mathematically, to the gravitational field. For example, work must be done to lift a body above the earth against gravitational force. Similarly, energy exchanges must occur in order to more electric charges in an electric field. Many difficulties due to the vector nature of electrics field can be avoided by potential rather than with force and electric field intensity. The use of electric potential extends into the field of current electricity and is basis to an understanding of circuits and all practical electrical devices.
