I was interviewed in Dec 2023.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease the voltage in electrical power transmission and distribution systems.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding receives electrical energy from the...
Maintenance is the process of ensuring the proper functioning and longevity of electrical systems and equipment.
Maintenance involves regular inspections, repairs, and replacements of electrical components.
It includes preventive maintenance to identify and address potential issues before they cause failures.
Maintenance also includes corrective actions to fix electrical problems and restore functionality.
Examples of elec...

Ohm's law defines the relationship between current and voltage in an electrical circuit.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it.
The equation for Ohm's law is I = V/R, where I is the current, V is the voltage, and R is the resistance.
This law helps in understanding and calculating the behavior of electrical circuits.
For example, if the volta...
There are several types of connections in motors, including star (Y) connection, delta (Δ) connection, and series connection.
Star (Y) connection: The three motor windings are connected in a Y shape, with one end of each winding connected to a common point.
Delta (Δ) connection: The three motor windings are connected in a triangle shape, with the end of each winding connected to the start of the next winding.
Series conne...

I applied via Recruitment Consultant and was interviewed in Sep 2021. There were 5 interview rounds.
Types of breakdown include thermal, dielectric, and electrostatic. Types of maintenance include corrective, preventive, and predictive.
Thermal breakdown occurs due to excessive heat and can cause insulation failure.
Dielectric breakdown occurs due to high voltage and can cause insulation failure.
Electrostatic breakdown occurs due to static electricity and can cause damage to electronic components.
Corrective maintenance ...

Qus on electrical engineering and general aptitude
MOSFET is a type of transistor used for amplification and switching of electronic signals.
MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.
It has three terminals: gate, source, and drain.
It is widely used in electronic devices such as computers, mobile phones, and power amplifiers.
MOSFETs are used in power electronics for switching applications due to their high switching speed and low on-resistance.
