- Q1. Tell me about yourself
- Q2. How does power flow from generation to end consumer
- Ans.
Power flows from generation to end consumer through a series of interconnected transmission and distribution systems.
Power is generated at power plants using various sources such as coal, natural gas, nuclear, hydro, wind, or solar energy.
The generated power is then transmitted over long distances through high-voltage transmission lines to substations.
At substations, the voltage is reduced and the power is distributed ...
- Q3. Basic BEE question
- Q4. College project
- Q5. What is relay and busbar
- Ans.
A relay is an electrically operated switch used to control a circuit by a separate low-power signal. A busbar is a metallic strip or bar used to distribute electrical power within a system.
Relay is used to control high-power circuits with a low-power signal
Busbar distributes electrical power within a system
Relay can be electromechanical or solid-state
Busbars are typically made of copper or aluminum
Examples: Electromech...

- Q1. What is transformer?
- Ans.
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used to step up or step down voltage in power distribution systems
Examples include power t...
- Q2. Types of transformer?
- Ans.
Types of transformers include step-up, step-down, isolation, autotransformer, and instrument transformer.
Step-up transformer increases voltage
Step-down transformer decreases voltage
Isolation transformer provides electrical isolation between primary and secondary windings
Autotransformer has a single winding with multiple taps
Instrument transformer is used for measuring current or voltage in high voltage circuits
- Q3. What is current transformer?
- Ans.
A current transformer is a type of instrument transformer that is used to measure alternating current.
Current transformers step down current to a safe level for measurement or protection purposes.
They have a primary winding connected in series with the circuit carrying the current to be measured.
The secondary winding is connected to measuring or protective devices.
Current transformers are commonly used in power systems...
- Q4. What is difference between current transformer and potential transformer?
- Ans.
Current transformer is used to measure current while potential transformer is used to measure voltage.
Current transformer is connected in series with the circuit being measured, while potential transformer is connected in parallel.
Current transformer steps down the current to a measurable level, while potential transformer steps down the voltage.
Current transformer is used for protection and metering purposes, while po...
- Q5. What is current
- Ans.
Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A).
It is the rate of flow of electric charge past a point in a circuit.
Current can be either direct current (DC) or alternating current (AC).
In a series circuit, the current is the same at all points.
In a parallel circuit, the total current is divided among the branches.
Ohm's Law relates current, voltage, and resistance: I = V/R.
- Q6. What is voltage
- Ans.
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
Voltage is the driving force that pushes electric current through a circuit
It is measured in volts (V)
Higher voltage means more potential energy available to move electrons
Voltage can be DC (direct current) or AC (alternating current)
Example: A battery provides a voltage of 1.5V to power a flashlight

- Q2. What is the type of motor
- Ans.
The type of motor refers to the classification based on the design and operation of the motor.
There are various types of motors such as DC motors, AC motors, synchronous motors, induction motors, etc.
The type of motor is determined by factors like the power source, speed control, and construction.
Each type of motor has its own advantages and applications in different industries.
For example, DC motors are commonly used ...

- Q1. Explain OOPs w.r.t Java
- Ans.
OOPs is a programming paradigm that uses objects to represent real-world entities. Java is an OOPs language.
OOPs stands for Object-Oriented Programming System
Java is a class-based OOPs language
Encapsulation, Inheritance, Polymorphism, and Abstraction are the four pillars of OOPs
Objects have state and behavior
Java supports interfaces, which allow for multiple inheritance
Example: A car can be represented as an object wit...
- Q2. Explain about the projects that you have worked on
- Q3. Explain how Java solves machine dependency of code execution
- Ans.
Java solves machine dependency by using bytecode and virtual machine.
Java code is compiled into bytecode which is platform-independent
The bytecode is executed by the Java Virtual Machine (JVM) which is platform-specific
JVM translates bytecode into machine code for the specific platform
This allows Java code to run on any platform with a JVM installed
Example: A Java program compiled on Windows can run on Linux or Mac as
