The electrical energy is said to be the ability of an electrical circuit to work which it produces by creating. This action which we are talking about can take many forms for example such as electromagnetic, thermal, mechanical, electrical, etc.
The energy which is said to be the electrical energy can be both created from batteries as well as the generators, dynamos, and photovoltaics, etc. These are stored for future use too using cells which are fuel, batteries, capacitors or we can say that the magnetic fields, etc. Thus the energy which is the electrical energy can be either created or stored.
Examples of Electrical Energy
For example, we can take a motor which converts electrical energy into mechanical or kinetic energy or we can say rotational energy. while a generator generally converts energy which is the kinetic energy literally back into energy which is said to be electrical energy to power a circuit. That is we can consider here the electrical machines which convert or change energy that is from one form to another by doing work.
We can again take another example of a lamp, light bulb or LED that is a light emitting diode which converts energy which is electrical energy into light energy and heat or thermal energy. Then energy which is electrical energy is said to be very versatile as it can be easily converted into many other different forms of energy.
What is Electricity Made of?
We have seen in this article that the unit which is of electrical charge is the Coulomb and that the electric charge flow around a circuit is used to represent a current flow. However we can say that as the symbol which is for a coulomb is denoted by the letter “C“, this can be confused with the symbol that is for Capacitance starting with C.
To avoid this confusion which is between both of them the common symbol used for electrical charge is the capital letter “Q” or small letter “q“, that is said to be basically standing for quantity. Thus we can say that hwew Q = 1 coulomb that is of charge or Q = 1C. Note that the charge which is denoted as Q that can be either positive written as +Q or negative -Q, that is an excess of either holes or electrons.
The charge flow around a closed circuit which is in the form of electrons is known as an electric current. However, we can say that the use which is of the expression “flow of charge” implies movement so this is to produce a current which is odf electrical charge must move. This then is said to lead to the question which is of what is making the charge move and then this is done by our old friend who is said to be as Voltage from above.
Difference is Between Electrical Energy and Power
The energy which is said to be the electrical energy defines the energy which is generated due to the movement that is of charge that is carried in a conductor.
While we can again say or consider here that the electrical power specifies the rate of consumption of electrical energy by a device.
The SI unit which is of electrical energy is said to be Joules. But the power which is electrical is measured in Watts or KWh.
