I applied via Walk-in and was interviewed in Nov 2021. There were 3 interview rounds.
Resistance is the measure of opposition to the flow of electric current in a material.
Resistance is caused by collisions between electrons and atoms in a material.
It is measured in ohms (Ω).
Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.
Materials with high resistance are called insulators, while materials with low resistance are called conductors.
Examples of...
Current is the flow of electric charge in a circuit.
Current is measured in amperes (A).
It is caused by the movement of electrons or other charged particles.
Current can flow in both directions in an alternating current (AC) circuit.
In a direct current (DC) circuit, current flows in only one direction.
Current can be calculated using Ohm's Law: I = V/R, where I is the current, V is the voltage, and R is the resistance.

I applied via Walk-in and was interviewed before Nov 2020. There was 1 interview round.
A circuit breaker is an electrical switch that automatically interrupts the flow of current when it exceeds a certain limit.
It is used to protect electrical circuits from damage caused by overloading or short circuits.
It works by detecting the excess current and tripping the switch to break the circuit.
It can be reset manually or automatically depending on the type of circuit breaker.
Examples include thermal circuit br...
A contactor is an electrical switch used for switching an electrical circuit on or off.
It is used to control electric motors, lighting, heating, and other electrical loads.
It consists of a coil, contacts, and an enclosure.
The coil generates a magnetic field that pulls the contacts together to close the circuit.
Examples include HVAC systems, elevators, and industrial machinery.
Contactor ratings are based on the amount o...
MCB stands for Miniature Circuit Breaker. It is an electrical switch that automatically shuts off the electrical circuit during an overload or short circuit.
MCB is a type of circuit breaker that is commonly used in residential and commercial buildings.
It is designed to protect electrical circuits from damage caused by overloading or short circuits.
MCBs are available in different current ratings and can be easily replac...
A motor is a device that converts electrical energy into mechanical energy to produce motion.
Motors are used in various applications such as electric vehicles, industrial machinery, and household appliances.
There are different types of motors such as DC motors, AC motors, stepper motors, and servo motors.
The basic principle of a motor is the interaction between a magnetic field and an electric current.
Examples of motor...
A current transformer is a device that measures the current flowing in a circuit by producing a proportional current in its secondary winding.
Consists of a primary winding and a secondary winding
Primary winding is connected in series with the circuit carrying the current to be measured
Secondary winding is connected to a measuring instrument or protective relay
Produces a current in the secondary winding that is proporti...

The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.
Furnace capacity is determined by the amount of heat it can produce.
It is usually measured in BTUs (British Thermal Units) or tons.
Higher capacity furnaces can produce more heat and are suitable for larger spaces.
For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000
Drive components in CCM department are the parts that enable the motor to function properly.
Drive components include motors, gears, belts, and pulleys.
They work together to transfer power from the motor to the machine.
The components must be properly sized and aligned to ensure efficient operation.
Examples of machines that use drive components include conveyor belts, pumps, and fans.
