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...
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...
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...
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
Yes, I know Java.
I have experience in Java programming.
I am familiar with Java syntax and concepts.
I have worked on Java projects in the past.
To retrieve data from the back end, you can use APIs or database queries.
Use API calls to fetch data from the back end server.
Execute database queries to retrieve data from the database.
Parse the response or query result to extract the required data.
Handle any necessary authentication or authorization for accessing the back end.
Examples: GET request to an API endpoint, SELECT query in SQL.
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
Print the level order traversal of binary tree in spiral form
Perform level order traversal of the binary tree
Alternate the direction of traversal for each level
Use a stack to reverse the order of nodes in each level
Print the nodes in the order of traversal
Find the maximum element in each subarray of size k in a given array.
Iterate through the array from index 0 to n-k.
For each subarray of size k, find the maximum element.
Store the maximum elements in a separate array.
Return the array of maximum elements.
To find the Kth largest element in two sorted arrays, we can use the merge step of merge sort algorithm.
Merge the two arrays into a single sorted array using a modified merge sort algorithm.
Return the Kth element from the merged array.
Merge two sorted arrays into one sorted array with expected time complexity of (m+n).
Use a two-pointer approach to compare elements from both arrays and merge them into the first array.
Start comparing elements from the end of both arrays and place the larger element at the end of the first array.
Continue this process until all elements from the second array are merged into the first array.
