# Circuit Globe All about Electrical and Electronics

Definition: The device which takes electrical energy is known as the electric load. In other words, the electrical load is a device that consumes electrical energy in the form of the current and transforms it into other forms like heat, light, work, etc. The electrical load may be resistive, inductive, capacitive or some combination between them. The term load is used in the number of ways.

• To indicates a device or a collection of the equipment which use electrical energy.
• For showing the power requires from a given supply circuit.
• The electrical load indicates the current or power passing through the line or machine.

The classifications of loads are shown in the figure below. The nature of the load depends on the load factor, demand factor, diversity factor, power factor, and a utilisation factor of the system. The different types of load are explained below in details.

The resistive load obstructs the flow of electrical energy in the circuit and converts it into thermal energy, due to which the energy dropout occurs in the circuit. The lamp and the heater are the examples of the resistive load. The resistive loads take power in such a way so that the current and the voltage wave remain in the same phase. Thus the power factor of the resistive load remains in unity. The inductive loads use the magnetic field for doing the work. The transformers, generators, motor are the examples of the load. The inductive load has a coil which stores magnetic energy when the current pass through it. The current wave of the inductive load is lagging behind the voltage wave, and the power factor of the inductive load is also lagging. In the capacitive load, the voltage wave is leading the current wave. The examples of capacitive loads are capacitor bank, three phase induction motor starting circuit, etc. The power factor of such type of loads is leading. ### Types of Electrical Loads in Power System

The total loads of an area depend on its population and living standard of the people. The different types of the loads in a power system are as follows.
