Electricity Loads

- Overview

An electrical load is any component of a circuit that consumes power or energy. It can also refer to the power consumed by a circuit. 

Here are some types of electrical loads:

  • Domestic load: The total energy consumed by electrical appliances in a household. This includes lights, fans, refrigerators, air conditioners, and mixers. The amount of domestic load depends on the living standard, weather, and type of residence.
  • Commercial load: Electrical loads used commercially, such as shop lighting, office appliances, and restaurant appliances. These appliances are usually connected for longer hours than domestic loads.
  • Resistive load: An electrical load that consists of a heating element, such as lamps, ovens, toasters, or space heaters. Resistive loads draw an electrical current in a sinusoidal waxing-and-waning pattern in sync with a sinusoidal variation in voltage.
  • Capacitive load: An AC electrical load in which the current wave reaches its peak before the voltage. Capacitive loads have both current and voltage waves. An example of a capacitive load is the flash of a camera.
  • Inductive load: Uses wire coils to store magnetic energy and create an inductive field so that the current wave lags behind the voltage wave. Inductive loads provide power to electric motors.
