Srinivas Fine Arts Interview Questions and Answers

Diodes are electronic components that allow current to flow in one direction. In the automation industry, diodes are used for various purposes.

• Rectifier diodes are used to convert AC power to DC power in automation systems.

• Zener diodes are used for voltage regulation and protection against voltage spikes.

• Light-emitting diodes (LEDs) are used as indicators in automation equipment.

• Schottky diodes are used for high-frequency applications and as voltage clamps.

• Varactor diodes are...read more

The operational voltage of TTL (Transistor-Transistor Logic) is typically 5 volts.

• TTL is a type of digital logic circuit that uses transistors to perform logic operations.

• The operational voltage of TTL is usually 5 volts, although there are variations like 3.3 volts TTL.

• TTL circuits are commonly used in computers, microcontrollers, and other electronic devices.

• Examples of TTL logic families include TTL, TTL/LS (Low-power Schottky), and TTL/HC (High-speed CMOS).

Star delta connection is a method used to reduce the starting current of induction motors.

• Star delta connection is commonly used in industrial applications.

• In star delta connection, the motor is initially connected in a star configuration for starting.

• After a certain time, the motor is switched to a delta configuration for normal operation.

• The star configuration reduces the voltage across each winding, thus reducing the starting current.

• The delta configuration provides higher...read more

ECL is a programming language used for data processing and analysis.

• ECL stands for Enterprise Control Language.

• It is primarily used in the HPCC Systems platform for big data analytics.

• ECL is declarative and allows users to define data transformations and operations.

• It supports parallel processing and can handle large volumes of data efficiently.

• ECL code is written in modules and can be easily reused and shared.

• Example: ECL code can be used to extract, transform, and load data...read more

AC motors and DC motors operate on different principles.

• AC motors operate on alternating current, while DC motors operate on direct current.

• AC motors use electromagnetic induction to generate a rotating magnetic field, while DC motors use a commutator and brushes to create a constant magnetic field.

• AC motors are commonly used in household appliances, industrial machinery, and electric vehicles, while DC motors are often found in battery-powered devices and automotive applicat...read more
