10+ Esjay Pharma Interview Questions and Answers

The type of electrical machine used in wind turbines for power generation is the induction generator.

• Induction generator is commonly used in wind turbines due to its simplicity, reliability, and low maintenance requirements.

• It operates on the principle of electromagnetic induction to convert mechanical energy from the wind into electrical power.

• Induction generators do not require a separate power source for excitation, making them suitable for variable speed wind turbines.

• Exa...read more

Yes, as a Junior Engineer Electrical, you should be physically capable of climbing a 92 meter wind turbine.

• Physical fitness is important for climbing such heights

• Proper safety training and equipment are necessary

A synchronous generator is a device that converts mechanical energy into electrical energy with a constant speed of rotation.

• Consists of a rotor and a stator

• Produces AC power at a fixed frequency

• Used in power plants, wind turbines, and hydroelectric plants

Current is the flow of electric charge through a conductor.

• Current is measured in Amperes (A).

• It is the rate of flow of electric charge past a point in a circuit.

• Current can be either direct current (DC) or alternating current (AC).

• In a series circuit, the current remains the same throughout.

• Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance.

Voltage is the difference in electric potential between two points in a circuit, measured in volts.

• Voltage is the force that pushes electric current through a circuit.

• It is measured in volts (V).

• Voltage is the potential difference between two points in a circuit.

• Higher voltage means more potential energy available to move electrons.

• Example: A battery with a voltage of 1.5V can power a small flashlight.

Clogging is the blockage or obstruction of a pipe, tube, or passage by foreign material or waste.

• Clogging occurs when foreign material or waste accumulates and restricts the flow of fluids or gases.

• Common examples of clogging include hair in a shower drain, food particles in a kitchen sink drain, or dirt in a vacuum cleaner filter.

• Clogging can lead to reduced efficiency, malfunction, or damage in various systems such as plumbing, HVAC, or machinery.

• Preventive measures like re...read more

Generator functions are special functions in Python that allow you to pause and resume execution, generating a sequence of values.

• Generator functions use the 'yield' keyword to return values one at a time

• They can be used to create iterators in a memory-efficient way

• Types of generators include generator expressions and generator functions

• Example: def my_generator(): yield 1 yield 2 yield 3
