I appeared for an interview in Aug 2023.
Time constant of an RC circuit is the time taken for the voltage across the capacitor to reach approximately 63.2% of its final value.
Time constant (τ) is calculated as the product of resistance (R) and capacitance (C) in the circuit, τ = R * C.
It represents the rate at which the capacitor charges or discharges in response to a step change in voltage.
A smaller time constant indicates a faster response of the circuit, w...
Comparators are electronic circuits that compare two voltages and output a digital signal based on the comparison. Band pass filter circuit allows only a certain range of frequencies to pass through.
Comparators are used in applications such as voltage level detection, waveform shaping, and pulse width modulation.
They have two input terminals for the voltages to be compared and one output terminal for the digital signal...

I applied via Referral and was interviewed before Apr 2023. There was 1 interview round.
Pumps, fans, gearboxes, compressors, motors, and generators are essential components in various mechanical systems.
Pumps are used to move fluids, such as water or oil, through a system.
Fans are used to create airflow for cooling or ventilation purposes.
Gearboxes are used to transmit power from one component to another at different speeds or torques.
Compressors are used to increase the pressure of a gas, such as in air ...

A diode is an electronic component that allows current to flow in one direction and blocks it in the opposite direction.
Diodes are made of semiconductor materials, such as silicon or germanium.
They have two terminals: an anode (positive terminal) and a cathode (negative terminal).
When a diode is forward-biased, it allows current to flow through it.
When a diode is reverse-biased, it blocks the current.
Diodes are commonl...
A diode is a two-terminal electronic component that allows current to flow in one direction and blocks it in the opposite direction.
A diode has an anode and a cathode terminal.
It is represented by a triangle with a line at the base.
The arrowhead of the triangle points towards the cathode terminal.
The line at the base represents the anode terminal.
The symbol of a diode is often accompanied by its part number or label.
Conductor, insulator, and semiconductor are materials with different electrical conductivity properties.
Conductor: Materials that allow the flow of electric current easily. Examples: copper, aluminum.
Insulator: Materials that do not allow the flow of electric current. Examples: rubber, glass.
Semiconductor: Materials with intermediate conductivity. Examples: silicon, germanium.

I appeared for an interview before Apr 2023, where I was asked the following questions.
A motor converts electrical energy into mechanical energy through electromagnetic principles.
Electric current flows through the motor's windings, creating a magnetic field.
The interaction between the magnetic field and rotor induces motion.
Types of motors include AC motors (e.g., induction motors) and DC motors (e.g., brushed motors).
Speed and torque can be controlled by varying voltage or frequency.
Applications range ...

All Cummins engine questions
Cummins engines are available in various types including diesel, natural gas, and hybrid options.
Cummins diesel engines are commonly used in heavy-duty trucks and construction equipment
Cummins natural gas engines are popular for use in buses and other transportation vehicles
Cummins offers hybrid engines that combine diesel and electric power for increased efficiency
Other types of Cummins engines include marine engines
There are two main types of stock: common stock and preferred stock.
Common stock represents ownership in a company and typically comes with voting rights.
Preferred stock usually does not have voting rights but has a higher claim on assets and earnings.
Stock can also be classified based on market capitalization (small-cap, mid-cap, large-cap) or sector (technology, healthcare, finance).
Thermostats can be categorized into mechanical, electronic, programmable, and smart thermostats.
Mechanical thermostats use a bimetallic strip to control temperature.
Electronic thermostats use electronic sensors to detect temperature changes.
Programmable thermostats allow users to set schedules for heating and cooling.
Smart thermostats can be controlled remotely via smartphone apps and may have features like learning al...
The question is asking about the engine specifications of a specific model.
Identify the specific model being referred to
Provide details about the engine specifications of that model
Include any unique features or upgrades of the engine
Cooling system is a mechanism used to remove heat from a space or substance to maintain a lower temperature.
Cooling systems can be found in various applications such as air conditioning units, refrigerators, and computer systems.
They typically involve the circulation of a coolant or refrigerant to absorb and transfer heat away from the desired area.
Cooling systems can be either air-cooled or liquid-cooled, depending on
