Caracteristicas de la carga

In the context of electrical engineering, understanding the characteristics of various loads is crucial for creating efficient and reliable systems. Loads can be classified by factors such as their dependence on electric service, type of consumer establishment, and geographical location, each influencing how power is distributed and managed.
