KESCo Interview Questions and Answers

A DC machine is an electrical machine that converts mechanical energy into direct current (DC) electrical energy.

• DC machines have two main types: DC motor and DC generator.

• DC motors convert electrical energy into mechanical energy, while DC generators convert mechanical energy into electrical energy.

• Examples of DC machines include electric cars, industrial machinery, and power plants.

Synchronous machine is an AC machine in which the rotor rotates at the same speed as the rotating magnetic field of the stator.

• Synchronous machines are commonly used in power generation and transmission systems.

• They operate at a constant speed determined by the frequency of the AC power supply.

• Synchronous machines can be either synchronous generators (alternators) or synchronous motors.

• They require a DC excitation sour...read more

A microprocessor is a small electronic device that functions as the central processing unit of a computer.

• Microprocessors are made up of millions of tiny components like transistors and resistors.

• They execute instructions and perform calculations for various tasks.

• Examples include Intel's Core i7, AMD's Ryzen, and ARM's Cortex processors.

A diode is a semiconductor device that allows current to flow in one direction only.

• Semiconductor device

• Allows current flow in one direction

• Commonly used in rectifiers and voltage regulators
