Induction motors are a type of AC motor where power is supplied to the rotor by electromagnetic induction.
Induction motors do not have any physical electrical connections between the stator and rotor.
They are widely used in various applications due to their simplicity, reliability, and low cost.
Examples of induction motors include squirrel cage motors and wound rotor motors.
Transformer types include step-up, step-down, isolation, autotransformer, and distribution transformers.
Step-up transformers increase voltage levels for long-distance transmission.
Step-down transformers decrease voltage levels for household use.
Isolation transformers provide electrical isolation between circuits.
Autotransformers have a single winding with taps for different voltage levels.
Distribution transformers supp

The laws of thermodynamics govern the behavior of energy in systems, while SI and CI engines are types of internal combustion engines.
The laws of thermodynamics include the first law (conservation of energy), second law (entropy always increases), and third law (absolute zero cannot be reached).
SI engines (spark ignition) use a spark plug to ignite the fuel-air mixture, commonly found in gasoline-powered vehicles.
CI en...

Was quite easy if you prepare and revise basics
Communication modules in PLCs are hardware components that allow the PLC to communicate with other devices or systems.
Communication modules provide various communication interfaces such as Ethernet, serial ports, Profibus, Profinet, etc.
They enable the PLC to exchange data with other PLCs, HMIs, SCADA systems, or external devices like sensors and actuators.
Some communication modules support wireless communication proto...
Power generation involves converting various forms of energy into electrical power, which is then distributed through a network of transmission lines and substations to end users.
Power generation involves converting mechanical, chemical, solar, wind, or nuclear energy into electrical power
The generated power is then transmitted through high-voltage transmission lines to substations
Substations step down the voltage for ...

Types of induction machines include squirrel cage induction motors and wound rotor induction motors.
Squirrel cage induction motors have a simple and rugged construction, suitable for constant speed applications.
Wound rotor induction motors have external resistors connected to the rotor windings, allowing for adjustable speed and high starting torque.
Other types include double cage induction motors and single-phase indu...
A combination of both standard and arc fault circuit breakers are used in my home.
Standard circuit breakers are used to protect against overloads and short circuits.
Arc fault circuit breakers are used to detect and prevent electrical fires caused by arcing faults.
Both types of circuit breakers provide different levels of protection for electrical circuits.
Examples: Square D QO series for standard circuit breakers, Siem
DC motors, transformers, synchronous and induction machines are all important components in electrical engineering.
DC motors are classified into various types such as brushed DC motors, brushless DC motors, and stepper motors.
Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Synchronous machines operate at a constant speed and are used in ...

I applied via Campus Placement and was interviewed in Aug 2023. There were 4 interview rounds.
In aptitude test , they asked questions regarding reasoning verbal, general knowledge and also about electrical subjects. 100 questions in 90min it was pretty tough and time consuming
They created a group of 8 as one group. My GD was online. My GD topic was "Impact of Iot in our lifes". They gave us 2min for preparation and 10min for discussion.
Mechatronics is a multidisciplinary field that combines mechanical engineering, electronics, computer science, and control engineering.
Combines mechanical engineering, electronics, computer science, and control engineering
Involves designing, developing, and controlling advanced systems
Examples include robotics, automated manufacturing systems, and automotive systems
BS4 engines comply with Bharat Stage 4 emission norms, while BS6 engines comply with Bharat Stage 6 emission norms.
BS4 engines have higher emissions of pollutants like NOx and PM compared to BS6 engines
BS6 engines have advanced emission control technologies like Selective Catalytic Reduction (SCR) and Diesel Particulate Filter (DPF)
BS6 engines are more fuel-efficient and environmentally friendly compared to BS4 engines
Mechatronics is the integration of mechanical, electrical, and computer engineering to create useful products and systems.
Automated manufacturing systems
Robotics
Automated guided vehicles
Smart home technology
Medical devices
Improving the performance of electrical vehicles can be achieved through various methods.
Increasing battery capacity for longer range
