STEEL MAX ROLLING MILLS Supervisor Interview Questions and Answers

Basic electronics and electrical questions

Q1. What is transformer
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.

• Examples of transformers include power transformers used in elec...read more

Q2. Explain Freaday law
Ans. 
Freaday's law states that the induced electromotive force (emf) in any closed circuit is equal to the negative rate of change of the magnetic flux through the circuit.
• Freaday's law is a fundamental principle in electromagnetism.

• It explains how a changing magnetic field can induce an electric current in a circuit.

• The induced emf is proportional to the rate of change of the magnetic flux.

• Mathematically, the equation for ...read more

Q3. Explain ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
• Ohm's Law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known.

• It also helps in determining the resistance in a circuit...read more

Q5. Induction motor different between square cage vs slippers ring
Ans. 
Square cage induction motors have a squirrel cage rotor with bars and end rings made of copper or aluminum, while slip ring induction motors have a wound rotor with external resistors connected to slip rings.
• Square cage induction motors have a simpler and more rugged construction compared to slip ring motors.

• Slip ring induction motors allow for external resistance control, enabling speed control and high starting torqu...read more

Q1. What is electicity,resistance,
Ans. 
Electricity is the flow of electric charge, while resistance is the measure of opposition to the flow of electric current.
• Electricity is the movement of electrons through a conductor.

• Resistance is the property of a material that hinders the flow of electric current.

• Resistance is measured in ohms (Ω).

• Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied and inverse...read more
