• Capacitors can be used to improve power factor in certain situations.

• Power Factor correction is ofte...read more

Star and Delta connections are used in three-phase AC systems to control voltage and current.

• Star connection is used when the load requires a lower voltage than the supply voltage.

• Delta connection is used when the load requires the same voltage as the supply voltage.

• Practically, star connection is achieved by connecting the three phases to a common point and the load to the other ends of the phases.

• Delta connection is achieved by connecting the end of one phase to the start o...read more

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease the voltage in electrical systems.

• They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

• The primary winding receives electrical energy and creates a magnetic field, which induces a voltage in the secondary winding.

• Transformers are common...read more

Induction motors are electric motors that work based on the principle of electromagnetic induction.

• Induction motors are commonly used in various applications, such as industrial machinery, HVAC systems, and household appliances.

• They consist of a stator and a rotor, with the stator containing the stationary windings and the rotor containing the rotating windings.

• When an alternating current is supplied to the stator windings, it creates a rotating magnetic field that induces cu...read more

Electricity can be categorized into different types based on its properties and usage.
