Q1. What is the another name of induction motor
Ans. 
Another name for induction motor is asynchronous motor.
• Asynchronous motor is commonly used in industrial applications.

• It operates at a slightly slower speed than the synchronous speed.

• Examples include squirrel cage induction motor and wound rotor induction motor.

Q3. What is exciter
Ans. 
An exciter is a device that supplies the field current to the rotor winding of a synchronous machine.
• Supplies field current to the rotor winding

• Helps in generating the magnetic field in the rotor

• Essential component in synchronous machines

• Can be either brushless or brush type

• Examples include static exciter and rotating exciter

Q1. Why we cannot operate transformer in dc supply
Ans. 
Transformers cannot operate on DC supply due to the absence of changing magnetic field required for induction.
• Transformers work on the principle of electromagnetic induction, which requires a changing magnetic field.

• DC supply produces a constant magnetic field, which does not induce a voltage in the secondary coil of the transformer.

• AC supply, on the other hand, produces a changing magnetic field, allowing for inductio...read more

Q1. Why we cannot measured transformer in kw
Ans. 
Transformers cannot be measured in kW because they do not consume power, they only transfer it.
• Transformers do not have any moving parts or internal power losses, so they do not consume power themselves

• The power rating of a transformer is given in kVA (kilovolt-amperes) which represents the maximum amount of power it can transfer

• The power factor of the load connected to the transformer determines the actual power in kW

Q1. What is the second law of thermodynamics?
Ans. 
The second law of thermodynamics states that the entropy of an isolated system always increases over time.
• Entropy of an isolated system always increases

• Heat cannot spontaneously flow from a colder body to a hotter body

• Efficiency of a heat engine is always less than 100%

• Examples: melting ice, burning wood

Q1. Name the boiler that does not need a steam drum.
Ans. 
Benson Boiler is a type of boiler that does not require a steam drum.
• Benson Boiler is a high-pressure, water tube boiler.

• It operates at supercritical pressure.

• The water is heated in a single pass through the evaporator tubes.

• It is commonly used in power plants.

• Examples include the Lethabo, Majuba, and Kendal power stations in South Africa.
