SKF Senior Electrical Engineer Interview Questions and Answers

Q1. What is the teransform
Ans. 
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Transformers are commonly used to step up or step down voltage levels in electrical systems.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

• The primary coil is connected to the input voltage source, while the secondary coil is connected to the outpu...read more

Q3. What is the voltage
Ans. 
Voltage is the difference in electric potential between two points.
• Voltage is measured in volts (V).

• It represents the potential energy per unit charge.

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

Q4. What is the ohm's low
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's Law is represented by the formula V = IR, where V is the voltage, I is the current, and R is the resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known, or determining the r...read more

Q3. Chemical effect of electric current
Ans. 
Electric current can cause chemical changes in substances it passes through.
• Electric current can cause electrolysis, which is the breakdown of a substance into its constituent elements or ions.

• This can be seen in the process of electroplating, where a metal is deposited onto a surface by passing an electric current through a solution containing ions of the metal.

• Electric current can also cause corrosion, as seen in the...read more

Q1. How many arthing in electric
Ans. 
Earthing is an important safety measure in electrical systems.
• Earthing provides a path for fault current to flow safely to the ground.

• There are different types of earthing systems such as TN, TT, and IT.

• The number of earthing points depends on the type of system and the size of the installation.

• For example, a small domestic installation may have one earth rod, while a large industrial installation may have multiple ear...read more
