- Q1. What is transformer and working principles of transformer
- Ans.
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They have two coils, primary and secondary, wound around a common magnetic core
When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil
The voltage in...
- Q2. What is motor working principles and testing of motor etc
- Ans.
Motor working principles involve the interaction between magnetic fields and electric currents to produce rotational motion.
Electric current is passed through a coil of wire, creating a magnetic field that interacts with the magnetic field of a permanent magnet to produce rotational force.
The direction of the current determines the direction of the rotation.
Motor testing involves measuring the motor's performance chara...

- Q1. Why power plug earth wire is bigger in size?
- Ans.
The power plug earth wire is bigger in size to ensure safety and prevent electrical shocks.
The earth wire provides a path for the current to flow in case of a fault or short circuit.
A larger wire size reduces resistance and allows for the safe dissipation of excess current.
It helps to protect individuals and equipment from electric shock hazards.
The earth wire is connected to the ground, which acts as a reference point...
- Q2. Which conductor of same size will take larger current Al or Cu?
- Ans.
Copper (Cu) conductor will take larger current than Aluminum (Al) conductor of the same size.
Copper has a higher electrical conductivity than Aluminum.
Copper has a lower resistivity than Aluminum.
Copper has better thermal conductivity than Aluminum.
Copper is more commonly used in high-current applications.
Aluminum is often used in overhead power transmission lines due to its lighter weight.
- Q3. What is pulse width modulation in VFD?
- Ans.
Pulse width modulation (PWM) is a technique used in VFD to control the speed of the motor by adjusting the width of the pulses of voltage supplied to the motor.
PWM is a method of controlling the amount of power delivered to a load without changing the voltage level.
In VFD, PWM is used to control the speed of the motor by varying the width of the pulses of voltage supplied to the motor.
The width of the pulses is control...

- Q1. Dol and star delta wiring scheme
- Ans.
DOL (Direct-On-Line) and star delta are two different wiring schemes used in electrical engineering for starting induction motors.
DOL wiring directly connects the motor to the power supply for starting, while star delta wiring initially starts the motor in star configuration and then switches to delta configuration for running.
DOL wiring is simpler and cheaper but causes high starting current, while star delta wiring r...

- Q2. How is alumina obtained from bauxite?
- Ans.
Alumina is obtained from bauxite through the Bayer process.
Bauxite is crushed and mixed with sodium hydroxide to form a slurry.
The slurry is heated and pressurized in a digester to dissolve the alumina content.
The resulting solution is cooled and filtered to remove impurities.
The purified solution is then heated to precipitate the alumina as a white powder.
The alumina powder is washed, dried, and calcined to produce pu...
- Q3. Reaction for Al extraction from alumina.
- Ans.
The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.
Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.
The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.
In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...
- Q4. Stainless steel production.
- Q5. Types of cast iron.
- Ans.
There are four main types of cast iron: gray iron, white iron, ductile iron, and malleable iron.
Gray iron is the most common type and has excellent castability and good machinability.
White iron is very hard and brittle, often used for wear-resistant applications.
Ductile iron has high strength and ductility, making it suitable for a wide range of applications.
Malleable iron is heat-treated to improve its strength and du
