Seemoan Services Interview Questions and Answers

Motors are rated in KW because they consume power, while transformers and generators are rated in KVA because they produce power.

• Motors convert electrical energy into mechanical energy, so they consume power and are rated in KW.

• Transformers and generators produce electrical energy, so they are rated in KVA based on their apparent power.

• KVA takes into account both the real power (KW) and the reactive power (KVAR) produc...read more

The type of motor used in ceiling fans is an induction motor.

• Ceiling fans typically use single-phase induction motors.

• These motors are designed to provide a constant speed and are efficient in converting electrical energy into mechanical energy.

• The motor consists of a stator and a rotor, with the stator being the stationary part and the rotor being the rotating part.

• The stator contains windings that create a rotating m...read more

A thermal power plant generates electricity by converting heat energy into mechanical energy.

• Thermal power plants use fossil fuels or nuclear energy to heat water and produce steam.

• The steam drives a turbine, which is connected to a generator that produces electricity.

• The heat source can be coal, natural gas, oil, or nuclear reactions.

• The steam is condensed back into water and recycled in a closed-loop system.

• Thermal p...read more

A program to generate a geometric progression (GP).

• Take the first term, common ratio and number of terms as input.

• Use a loop to calculate each term of the GP.

• Print the generated GP as output.

A program to print factorial using recursion

• Define a function to calculate factorial recursively

• Base case: if the number is 0 or 1, return 1

• Recursive case: multiply the number with factorial of (number - 1)

• Print the factorial of a given number

OOP is a programming paradigm based on the concept of objects, which can contain data and code.

• OOP stands for Object-Oriented Programming

• It focuses on creating objects that interact with each other to solve a problem

• Encapsulation, inheritance, and polymorphism are key concepts in OOP

• Example: A car object can have properties like color, make, and model, and methods like start and stop

• OOP promotes code reusability and ma

Caching is the process of storing frequently used data in a temporary storage to reduce access time. LRU caching removes least recently used data.

• Caching improves performance by reducing access time to frequently used data

• LRU (Least Recently Used) caching removes the least recently used data to make space for new data

• LRU cache can be implemented using a doubly linked list and a hash map

• When a cache hit occurs, the acce...read more
