Defining Electrical Energy
Electrical energy, in its essence, is the energy derived from the movement of electric charges, primarily electrons, through a conductive medium. This phenomenon results from the transfer of energy occurring when electrons transition between atoms, a process scientifically termed as work. The quantification of this energy is typically expressed in joules (J), while its manifestation as electricity is measured in watts (W) Electrical Energy | Definition, Concept & Examples.
The Science Behind Electrical Energy
Electric Charges and Their Movement
The fundamental principle underlying electrical energy is the flow of electrons through a conductor, induced by a difference in electrical potential. This potential difference, quantified in volts, generates an electric current, the magnitude of which is measured in amperes. The interaction between these charged particles, manifesting as electrical attraction or repulsion, constitutes the basis for electrical energy’s capacity to perform work What is electrical energy? – Iberdrola.
Measuring Electrical Energy
The quantification of electrical energy employs various units, with the kilowatt-hour (kWh) being the most prevalent in commercial and residential contexts. The relationship between energy, power, and time is encapsulated in the formula:
Energy (kWh) = Power (kW) × Time (hours)
