I was interviewed in Jan 2025.
I applied via Campus Placement and was interviewed in Aug 2024. There was 1 interview round.
Electrical energy is the energy derived from electric potential energy or kinetic energy of charged particles.
Electrical energy is the energy that is associated with the flow of electric charge.
It can be converted into other forms of energy such as mechanical, thermal, or light energy.
Examples include the energy used to power electrical devices like light bulbs, refrigerators, and computers.
An electronic device is a device that operates using electronic circuits and components to perform various functions.
Operates using electronic circuits and components
Performs various functions
Examples: smartphones, laptops, tablets, TVs, digital cameras
Resistance is the opposition to the flow of electric current in a material.
Resistance is measured in ohms (Ω).
It is caused by collisions between electrons and atoms in a material.
Materials with high resistance are insulators, while those with low resistance are conductors.
Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.
Copper is the best conductor due to its high conductivity and affordability.
Copper is the most commonly used conductor in electrical wiring
It has high electrical conductivity, second only to silver
Copper is also relatively affordable compared to other high conductivity metals like silver or gold
Types of AC motors include induction motors, synchronous motors, and brushed and brushless DC motors.
Induction motors: most commonly used type, simple design, reliable, low cost
Synchronous motors: maintain constant speed, used in applications requiring precise speed control
Brushed DC motors: use brushes to conduct current, simple design, lower cost
Brushless DC motors: no brushes, more efficient, longer lifespan, higher...
An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.
Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.
They do not require any physical connection between the rotor and the stator, making them more reliable and maintenance-free.
The speed of an induction motor is determined by the frequency of the AC...
Advantages of synchronous motor include high efficiency, power factor correction, and constant speed.
High efficiency: Synchronous motors operate at a higher efficiency compared to induction motors, making them ideal for applications where energy savings are important.
Power factor correction: Synchronous motors help improve the power factor of the system, leading to reduced electricity costs and better utilization of el...
I applied via Job Fair and was interviewed in Feb 2024. There was 1 interview round.
Iron ore pellets are small spherical balls of iron ore used in the production of steel.
Iron ore pellets are created by agglomerating fine iron ore concentrate in a balling drum or disc.
They are typically around 6-16 mm in size and have a high iron content.
Iron ore pellets are used as raw material in blast furnaces for the production of steel.

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

Proficient in Java with experience in developing web applications using Spring framework
Familiar with Python for data analysis and machine learning
Experience in C++ for developing high-performance applications
Also familiar with HTML, CSS, and JavaScript for front-end development
Class is a blueprint for creating objects, encapsulation is the process of hiding data and methods within a class.
Class is a template or blueprint that defines the properties and behaviors of an object.
Encapsulation is the process of bundling data and methods together within a class, hiding the internal details from the outside world.
Other features of OOP include inheritance, polymorphism, and abstraction.
Inheritance a...
