Shri Gang Industries Allied Products Electrical Technician Interview Questions and Answers

AC and DC are two types of electrical current with different characteristics.

• AC stands for alternating current, while DC stands for direct current.

• AC periodically changes direction, while DC flows in one direction.

• AC is used for power transmission over long distances, while DC is used for electronic devices.

• AC can be easily converted to different voltages using transformers, while DC requires converters or inverters.

• Ex...read more

Single-phase and three-phase supply differ in the number of power lines and voltage waveform.

• Single-phase supply has one power line and a sinusoidal voltage waveform.

• Three-phase supply has three power lines and a balanced sinusoidal voltage waveform.

• Single-phase supply is commonly used in residential applications.

• Three-phase supply is used in industrial and commercial applications.

• Three-phase supply provides higher pow...read more

Kirchhoff's current law states that the total current entering a junction is equal to the total current leaving the junction.

• The sum of all currents entering a junction is equal to the sum of all currents leaving the junction.

• This law is based on the principle of conservation of charge.

• It is used to analyze circuits and determine unknown currents.

• For example, if a junction has three currents entering and two currents l...read more

The statement refers to Kirchhoff's Current Law which states that the sum of currents entering a node is equal to the sum of currents leaving the node.

• Kirchhoff's Current Law is a fundamental law in electrical engineering

• It is also known as Kirchhoff's First Law or KCL

• The law applies to any node in an electrical circuit

• The algebraic sum of currents entering the node is equal to the algebraic sum of currents leaving the...read more

Newton's third law states that for every action, there is an equal and opposite reaction.

• Newton's third law is also known as the law of action and reaction.

• It means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

• For example, if you push a wall, the wall pushes back with an equal amount of force.

• This law is applicable to all types of for...read more

The laws of thermodynamics describe the behavior of energy in a system. Entropy always increases in a closed system.

• The first law states that energy cannot be created or destroyed, only transferred or converted.

• The second law states that the total entropy of a closed system always increases over time.

• The third law states that as temperature approaches absolute zero, the entropy of a system approaches a minimum.

• Entropy ...read more
