Thus “Work” is the name we give to the process of energy. The work done is stored in the flow of electrons as energy. Then electrical energy is very versatile as it can be easily converted into many other different forms of energy.įor electrical energy to move electrons and produce a flow of current around a circuit, work must be done, that is the electrons must move by some distance through a wire or conductor. Another example is a lamp, light bulb or LED (light emitting diode) which convert electrical energy into light energy and heat (thermal) energy. That is electrical machines convert or change energy from one form to another by doing work. For example, a motor converts electrical energy into mechanical or kinetic (rotational) energy, while a generator converts kinetic energy back into electrical energy to power a circuit. But for energy to do any useful work it must be converted from one form into something else. We remember from our school science classes that the “ The Law of the Conservation of Energy” states that energy cannot be created or destroyed, only converted. Thus electrical energy can be either created or stored. or stored for future use using fuel cells, batteries, capacitors or magnetic fields, etc. Electrical energy can be both created from batteries, generators, dynamos, and photovoltaics, etc. ![]() This action can take many forms, such as thermal, electromagnetic, mechanical, electrical, etc. Your browser does not support the audio element.Electrical Energy is the ability of an electrical circuit to produce work by creating an action. Listen to a recorded reading of this page:.Take a ten question quiz about this page.One horsepower is equal to the power it takes to lift 550 pounds up one foot in one second.The power exerted by the Space Shuttle rockets at lift-off is around 12 billion watts.This is power over time which is actually a measurement of energy used and not power. The "power" bill we get in the mail is usually billed in kilowatt hours. ![]()
