I applied via Naukri.com and was interviewed before Sep 2023. There was 1 interview round.
A generator is a device that converts mechanical energy into electrical energy.
Generates electricity through electromagnetic induction
Common types include diesel generators, gas generators, and wind turbines
Used in power plants, homes, and businesses for backup power
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 levels in power distribution
Examples include power tr...

*A and B invest in a business in the ratio 3 : 2. If 5% of the total profit goes to charity and A's share is Rs. 855, the total profit is?
*Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:
Transformers are rated in kVA because it takes into account both active power (KW) and reactive power (KVAR). Transformer losses include copper losses and iron losses.
Transformers are rated in kVA because they handle both active power (KW) and reactive power (KVAR).
kVA rating considers the total power (apparent power) that the transformer can handle, including the power needed for magnetizing the core.
Transformer losse...
Generator produces direct current while alternator produces alternating current. Different cables used for transmission include coaxial, twisted pair, and fiber optic cables.
Generator produces direct current (DC) while alternator produces alternating current (AC)
Generator uses slip rings and brushes for transmission while alternator uses a commutator
Different cables used for transmission include coaxial, twisted pair,
Motors operate based on the principle of electromagnetic induction, converting electrical energy into mechanical energy.
Motors work by creating a magnetic field through the flow of current in a coil of wire.
This magnetic field interacts with a permanent magnet or another magnetic field, causing the coil to rotate.
The rotation of the coil is then used to drive mechanical systems, such as fans, pumps, or conveyor belts.

I applied via Walk-in and was interviewed in Nov 2021. There was 1 interview round.
Underground cables typically have multiple layers for insulation and protection.
Underground cables usually have three layers: conductor, insulation, and protective sheath
The conductor layer carries the electrical current
The insulation layer prevents leakage of current and protects against environmental factors
The protective sheath provides additional protection from moisture, chemicals, and physical damage

A circuit breaker is an automatic electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
It is a safety device that automatically interrupts the flow of current in a circuit when it exceeds a safe level
It is used to protect electrical equipment from damage due to overcurrent
It can be reset after tripping, unlike a fuse which needs to be replaced
It comes in different ...
DC motors and AC motors are two types of electric motors commonly used in various applications.
DC motors operate using direct current, while AC motors operate using alternating current.
DC motors are typically used in applications that require high torque at low speeds, such as in electric vehicles and robotics.
AC motors are commonly used in household appliances, industrial machinery, and HVAC systems.
DC motors are simp...
I applied via Campus Placement and was interviewed before May 2022. There were 2 interview rounds.
Capacitance is the ability of a body to store an electric charge. Inductance is the ability of a coil to store energy in a magnetic field.
Capacitance is measured in Farads (F)
Capacitors are used to store energy in electronic circuits
Inductance is measured in Henrys (H)
Inductors are used in electronic circuits to store energy in a magnetic field
Both capacitance and inductance are important in AC circuits
Different types of cables used for transmissions include coaxial, twisted pair, fiber optic, and ribbon cables.
Coaxial cables are used for high-frequency transmissions and have a copper core surrounded by insulation and a braided shield.
Twisted pair cables are used for low-frequency transmissions and have two insulated copper wires twisted together.
Fiber optic cables use light to transmit data and are made of glass or ...
