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. 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

Q2. Law of thermodynamics
Ans. 
The laws of thermodynamics describe how energy behaves in a system.
• First law: Energy cannot be created or destroyed, only transferred or converted.

• Second law: Entropy in a closed system will always increase over time.

• Third law: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• Examples: A car engine converting fuel into motion (1st law), a cup of hot coffee cooling down (2nd la
