Wipro PARI Site Support Engineer Interview Questions, Process, and Tips

The type of current refers to the flow of electric charge in a circuit.

• There are two main types of current: direct current (DC) and alternating current (AC).

• DC flows in one direction continuously, while AC changes direction periodically.

• Examples of DC sources include batteries, while examples of AC sources include power outlets.

• The type of current used depends on the application and requirements of the circuit.

There are two main types of motors: AC motors and DC motors.

• AC motors: Induction motors, synchronous motors

• DC motors: Brushed DC motors, brushless DC motors

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

• Consists of two coils of wire, known as primary and secondary windings

• Works on the principle of electromagnetic induction

• Used to step up or step down voltage levels in electrical circuits

• Commonly used in power distribution systems

• Examples include power transformers, distribution transfor

Electrical equipment deals with electricity, while electronics equipment deals with electronic signals and circuits.

• Electrical equipment uses electricity as a power source, while electronics equipment uses electronic signals.

• Electrical equipment includes items like power cables, transformers, and circuit breakers, while electronics equipment includes items like computers, smartphones, and televisions.

The angle between three phase windings is 120 degrees.

• The angle between each phase in a three-phase system is 120 degrees.

• This is because 360 degrees divided by 3 phases equals 120 degrees.

• Understanding the phase angles is important for proper functioning of electrical systems.
