CIR Group Interview Questions and Answers

Rectifier, types of motor, difference between servo motor and induction motor

• Rectifier is an electrical device that converts alternating current (AC) to direct current (DC)

• Types of motors include DC motors, AC motors, servo motors, and induction motors

• Servo motors are used in applications that require precise control of position, velocity, and acceleration

• Induction motors are commonly used in industrial applications du...read more

An encoder is a device used to convert motion or position into a coded signal.

• Encoders are commonly used in robotics, CNC machines, and industrial automation.

• They can be either absolute or incremental, with absolute encoders providing a unique code for each position and incremental encoders providing a relative change in position.

• Encoders can be rotary or linear, depending on the type of motion being measured.

• They are ...read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to either step up or step down voltage levels.

• Step down transformers decrease voltage levels, while step up transformers increase voltage levels.

• Types of transformers include power transformers, distribution transformers, isolation transformers, autotransformers, and...read more

PLC stands for Programmable Logic Controller. It is an industrial computer used to automate processes.

• PLCs are used to control and monitor industrial processes such as assembly lines, power plants, and water treatment facilities.

• They are programmed using ladder logic or other programming languages.

• PLCs can be used to control various types of equipment such as motors, valves, and sensors.

• They are designed to operate in ...read more

The full form of A.C. current is Alternating Current.

• A.C. current stands for Alternating Current.

• It is a type of electric current that periodically reverses direction.

• It is commonly used in household electrical systems and power grids.

• Unlike direct current (D.C.), A.C. current can easily be transformed to different voltage levels.

• Examples of A.C. current include the electricity supplied by utility companies and the pow

The full form of D.C. current is Direct Current.

• D.C. stands for Direct Current.

• It is a type of electrical current that flows in one direction only.

• It is commonly used in batteries and electronic devices.

• The opposite of D.C. current is A.C. current, which alternates direction.

• D.C. current is measured in amperes (A).
