Q1. Explain about hydro power station?
Ans. 
A hydro power station is a facility that generates electricity by using the energy of falling water.
• Water is stored in a reservoir and released through turbines to generate electricity

• Hydro power is a renewable energy source

• Hydro power stations can be large or small scale

• Examples include the Hoover Dam in the US and the Three Gorges Dam in China

Q2. Explain How motor produces torque?
Ans. 
A motor produces torque by creating a magnetic field that interacts with the current flowing through the motor's coils.
• The motor's coils are energized with an electrical current, which creates a magnetic field.

• The magnetic field interacts with the magnetic field of the motor's permanent magnets, causing the rotor to turn.

• The amount of torque produced by the motor is proportional to the strength of the magnetic field an...read more

Q3. What are different types of motor. What is back emf and does back emf is present in both DC and AC motor
Ans. 
Different types of motors include DC, AC, stepper, servo, etc. Back EMF is present in both DC and AC motors.
• DC motors: brushed, brushless, series, shunt, compound

• AC motors: synchronous, asynchronous, induction

• Back EMF is the voltage generated in the opposite direction to the applied voltage

• Back EMF is present in both DC and AC motors

• Back EMF is used to control the speed of the motor

Q5. How does electric horn produces sound.
Ans. 
Electric horn produces sound by using an electromagnet to vibrate a diaphragm.
• Electric current flows through the coil of an electromagnet.

• The magnetic field produced by the electromagnet attracts and repels a metal diaphragm.

• The diaphragm vibrates rapidly, producing sound waves.

• The sound waves are amplified by a horn or resonator.

• The pitch and volume of the sound can be adjusted by changing the frequency and amplitude ...read more

Q1. What is the difference between two-stroke and four-stroke engines?
Ans. 
Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines require four strokes.
• Two-stroke engines have a simpler design and are lighter, making them suitable for applications like chainsaws and mopeds.

• Four-stroke engines are more fuel-efficient and produce lower emissions, commonly found in cars and larger motorcycles.

• In two-stroke engines, the power stroke occurs every revolutio...read more

Q2. What is the Carnot cycle?
Ans. 
The Carnot cycle is a theoretical thermodynamic cycle that defines the maximum efficiency of heat engines.
• Consists of four reversible processes: two isothermal and two adiabatic.

• The cycle operates between two heat reservoirs: a hot reservoir and a cold reservoir.

• Example: Idealized heat engine operating between boiling water and ice.

• Efficiency depends on the temperature difference between the reservoirs.

• Carnot efficienc...read more
