Q1. How is power transmitted to engine?
Ans. 
Power is transmitted to the engine through a system of belts, gears, and shafts connected to the engine's crankshaft.
• Power is typically transmitted from the engine to the wheels through a transmission system.

• In a manual transmission, power is transmitted through a clutch, gearbox, and driveshaft.

• In an automatic transmission, power is transmitted through a torque converter and planetary gearset.

• Some vehicles use a CVT (...read more

Q1. What is data structures in python
Ans. 
Data structures in Python are ways of organizing and storing data to make it easier to access and manipulate.
• Data structures in Python include lists, tuples, dictionaries, sets, and arrays.

• Lists are ordered collections of items, tuples are immutable sequences, dictionaries are key-value pairs, sets are unordered collections, and arrays are used for numerical data.

• Data structures help optimize operations like searching,...read more

Q1. What are different types of windings in transformer?
Ans. 
Different types of windings in transformers include primary winding, secondary winding, and tertiary winding.
• Primary winding: receives electrical power from the source

• Secondary winding: delivers electrical power to the load

• Tertiary winding: used in special transformers for specific applications

• Auto-transformer winding: single winding used as both primary and secondary

• Leakage winding: used to reduce leakage flux in the

Q3. What is modulation
Ans. 
Modulation is the process of varying a carrier signal's properties to transmit information.
• Modulation involves changing one or more properties of a high-frequency periodic waveform, called the carrier signal, in proportion to a signal to be transmitted.

• Common types of modulation include Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).

• Modulation allows for the efficient transmission of in...read more

Q4. What are different types of losses in a transformer
Ans. 
Different types of losses in a transformer include copper losses, iron losses, and stray losses.
• Copper losses: Also known as I^2R losses, occur in the windings due to resistance.

• Iron losses: Also known as core losses, occur in the core due to hysteresis and eddy currents.

• Stray losses: Occur due to leakage flux and imperfect magnetic coupling.

• Eddy current losses: Occur in the core due to circulating currents induced by ...read more
