I applied via Campus Placement and was interviewed in Jan 2024. There was 1 interview round.
Induction motors work on the principle of electromagnetic induction to generate rotating magnetic fields.
Induction motors have a stator with a set of windings that are connected to an AC power source.
When the AC power is applied, it creates a rotating magnetic field in the stator.
This rotating magnetic field induces currents in the rotor bars, causing it to rotate.
The rotor never catches up to the speed of the rotating...
Illumination refers to the amount of light present in a space, measured in lux or foot-candles.
Illumination is crucial for visibility and safety in indoor and outdoor environments.
It is measured using units such as lux or foot-candles.
Proper illumination levels are important in workplaces, homes, and public spaces.
Examples of illumination sources include natural light, light fixtures, and streetlights.
Switch gear is a combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.
Switch gear is used to control the flow of electricity in a power system.
It is essential for protecting electrical equipment from damage due to overloads or short circuits.
Common applications of switch gear include power distribution, industrial plants, and electrical subst
Transformers are classified based on their construction, cooling methods, and voltage levels.
Based on construction: Core type and Shell type transformers
Based on cooling methods: Oil immersed, Dry type, and Water cooled transformers
Based on voltage levels: Step-up and Step-down transformers
Examples: Distribution transformer, Power transformer, Auto transformer

Ohm's law is limited to linear, passive circuits with constant temperature and material properties.
Ohm's law only applies to linear circuits where voltage is directly proportional to current.
It assumes constant temperature and material properties, which may not always be the case.
Non-linear components like diodes and transistors do not follow Ohm's law.
Ohm's law does not account for reactive components like capacitors ...
It contains basic logical reasoning questions

Resistance is the opposition to the flow of electric current, while machines are devices that convert energy from one form to another.
Resistance is measured in ohms and is caused by the material and dimensions of a conductor.
Machines include motors, generators, transformers, and other devices that use electrical energy to perform work.
Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is vo
Machines operate based on various principles such as electromagnetic, mechanical, thermal, and chemical principles.
Machines convert one form of energy into another to perform work
Electromagnetic machines use the principles of electricity and magnetism, like motors and generators
Mechanical machines use moving parts to transfer and transform energy, like engines and gears
Thermal machines use heat to generate power, like ...
