Padmanabh Innovations Interview Questions, Process, and Tips

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

Logic to reverse a string without using string functions

• Iterate through the string from the last character to the first

• Create a new string and append each character to it in reverse order

• I have a degree in Computer Science

• I have worked with Java, Python, and JavaScript

• I have experience with front-end frameworks like React and Angular

• I have developed mobile apps using React Native

• I am familiar with Agile methodologies

I have a passion for software development and enjoy the challenges it presents.

• I have always been interested in technology and programming

• I enjoy problem-solving and finding efficient solutions

• I believe software engineering is a constantly evolving field with endless opportunities for growth

A program to check if a given number is prime or not.

• A prime number is a number that is only divisible by 1 and itself.

• Start checking from 2 up to the square root of the number.

• If the number is divisible by any number in the range, it is not prime.

• Otherwise, it is prime.

• Optimization: check only odd numbers after 2.

Fibonacci program generates a series of numbers where each number is the sum of the two preceding ones.

• The program can be implemented using recursion or iteration.

• The first two numbers in the series are always 0 and 1.

• The next number is the sum of the previous two numbers.

• Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418,...read more
