I applied via Company Website and was interviewed in Feb 2021. There was 1 interview round.
AC and DC are two types of electrical current with different characteristics.
AC stands for alternating current, while DC stands for direct current.
AC periodically changes direction, while DC flows in one direction.
AC is used for power transmission over long distances, while DC is used for electronic devices.
AC can be easily converted to different voltages using transformers, while DC requires converters or inverters.

Single-phase and three-phase supply differ in the number of power lines and voltage waveform.
Single-phase supply has one power line and a sinusoidal voltage waveform.
Three-phase supply has three power lines and a balanced sinusoidal voltage waveform.
Single-phase supply is commonly used in residential applications.
Three-phase supply is used in industrial and commercial applications.
Three-phase supply provides higher pow...
Kirchhoff's current law states that the total current entering a junction is equal to the total current leaving the junction.
The sum of all currents entering a junction is equal to the sum of all currents leaving the junction.
This law is based on the principle of conservation of charge.
It is used to analyze circuits and determine unknown currents.
For example, if a junction has three currents entering and two currents l...
The statement refers to Kirchhoff's Current Law which states that the sum of currents entering a node is equal to the sum of currents leaving the node.
Kirchhoff's Current Law is a fundamental law in electrical engineering
It is also known as Kirchhoff's First Law or KCL
The law applies to any node in an electrical circuit
The algebraic sum of currents entering the node is equal to the algebraic sum of currents leaving the...
Newton's third law states that for every action, there is an equal and opposite reaction.
Newton's third law is also known as the law of action and reaction.
It means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
For example, if you push a wall, the wall pushes back with an equal amount of force.
This law is applicable to all types of for...

The laws of thermodynamics describe the behavior of energy in a system. Entropy always increases in a closed system.
The first law states that energy cannot be created or destroyed, only transferred or converted.
The second law states that the total entropy of a closed system always increases over time.
The third law states that as temperature approaches absolute zero, the entropy of a system approaches a minimum.

A group of individuals working together towards a common goal or objective.
Teamwork and collaboration are essential for success.
Roles and responsibilities are clearly defined within a team.
Effective communication is crucial for a team's success.
Trust and respect are important for building a strong team dynamic.
Examples of teams include sports teams, project teams, and departmental teams.
I applied via Approached by Company and was interviewed in May 2024. There were 2 interview rounds.
Basic maths physics science and grammer
Technical discussion regarding work
I appeared for an interview before Feb 2024.
The subjects of study include Physics, Chemistry, and Mathematics.
The process of interviewing involves preparation, conducting the interview, evaluating candidates, and making a decision.
Preparation: Define job requirements, review resumes, and create interview questions.
Conducting the interview: Ask questions, assess candidate skills, and discuss job expectations.
Evaluating candidates: Compare qualifications, consider cultural fit, and gather feedback from interviewers.
Making a deci...
Different types of interviewing techniques include behavioral, situational, panel, group, and phone interviews.
Behavioral interviews focus on past experiences and how they relate to the job
Situational interviews present hypothetical scenarios to assess problem-solving skills
Panel interviews involve multiple interviewers asking questions
Group interviews assess how candidates interact with others
Phone interviews are cond
I applied via LinkedIn and was interviewed in Oct 2023. There were 4 interview rounds.

Discuss how to meet demands with less production
Star delta control diagram is a method of starting three-phase motors.
Used to reduce the starting current of the motor
Involves connecting the motor windings in a star configuration during starting
After a certain time, the windings are switched to a delta configuration for normal operation
Commonly used in industrial applications
Helps to prolong the life of the motor
PLC stands for Programmable Logic Controller, a digital computer used for automation of electromechanical processes.
PLC is used in industrial automation to control machinery and processes.
It is programmed using ladder logic or other programming languages.
PLC can monitor inputs and outputs, and make decisions based on programmed logic.
Examples of PLC applications include manufacturing, transportation, and energy managem...
Star delta starter is used to reduce starting current and protect the motor.
Reduces starting current by starting the motor in star configuration and then switching to delta configuration
Protects the motor from damage due to high starting current
Used for motors with high starting current, such as those with high horsepower or low starting resistance
Commonly used in industrial applications, such as pumps, compressors, an
There are many types of sensors used in electrical work.
There are temperature sensors, motion sensors, light sensors, and pressure sensors.
Other types of sensors include humidity sensors, gas sensors, and proximity sensors.
Sensors can be used to detect changes in the environment and trigger actions or alarms.
Different sensors have different applications and are used in various industries.
As an electrician, it is import...
VFD stands for Variable Frequency Drive. It is used to control the speed of an electric motor.
VFD is an electronic device that controls the frequency and voltage supplied to an electric motor.
It is used to vary the speed of the motor, which can help save energy and reduce wear and tear on the motor.
VFDs are commonly used in HVAC systems, pumps, and other industrial applications.
They can also be used to control the spee...
The current required by a 6.1hp motor depends on the voltage it operates on.
The current required by the motor can be calculated using the formula: Current (A) = Power (W) / Voltage (V)
Assuming the motor operates on 220V, the current required would be around 27.7A
However, if the motor operates on a different voltage, the current required would be different
Factors like the motor's efficiency and power factor can also aff
An air compressor is a machine that compresses air and stores it in a tank for later use.
Check the oil level and drain the water from the tank before starting
Connect the air hose to the compressor and the tool you want to use
Turn on the compressor and wait for the tank to fill with compressed air
Adjust the pressure regulator to the desired level
Use the tool and turn off the compressor when finished
Regularly maintain th...
