Daikin Airconditioning India Pvt. Ltd. Junior Engineer Interview Questions and Answers

Any one technical questions from Electrical branch.

Q1. What is current
Ans. 
Current is the flow of electric charge in a circuit.
• Current is measured in Amperes (A)

• It is the rate of flow of electric charge through a conductor

• There are two types of current - AC (alternating current) and DC (direct current)

• Example: A light bulb connected to a battery has current flowing through it

Q2. What is voltage
Ans. 
Voltage is the difference in electric potential between two points in a circuit, measured in volts.
• Voltage is the driving force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage can be positive or negative, depending on the direction of current flow

• Higher voltage means more energy available to push current through a circuit

• Examples: A battery provides voltage to power a flashlight, a wall...read more

Q3. What is Resistance
Ans. 
Resistance is the opposition to the flow of electric current in a circuit.
• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a material.

• Higher resistance means lower current flow.

• Examples of materials with high resistance include rubber and glass.

• Examples of materials with low resistance include copper and silver.

Q1. What is kirchoff law
Ans. 
Kirchhoff's law refers to two laws in circuit theory: Kirchhoff's current law and Kirchhoff's voltage law.
• Kirchhoff's current law states that the total current entering a junction is equal to the total current leaving the junction.

• Kirchhoff's voltage law states that the sum of the electromotive forces in any closed loop of a circuit is equal to the sum of the potential drops in that loop.

• These laws are fundamental in a...read more

Q1. Explain COP of chiller
Ans. 
COP of a chiller stands for Coefficient of Performance, which is a measure of the efficiency of a chiller system.
• COP is calculated as the ratio of cooling output to the energy input required to produce that cooling output.

• A higher COP value indicates a more efficient chiller system.

• COP can be calculated using the formula: COP = Cooling Output / Energy Input.

• For example, if a chiller has a COP of 4, it means that for ev...read more

Q3. What is flywheel in engine
Ans. 
A flywheel in an engine is a rotating mechanical device used to store rotational energy.
• Flywheels help to maintain a constant speed of the engine by storing energy during the power stroke and releasing it during the non-power strokes.

• They also reduce vibrations and provide smoother operation of the engine.

• In vehicles, flywheels are commonly used in manual transmissions to assist in smooth gear changes.

• Flywheels are typ...read more
