Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What machine is attached to a generator and rotates a generator to generate electricity?
A
wheel
B
turbine
C
axle
D
None of the above
Explanation: 

Detailed explanation-1: -The rotor is attached to the turbine shaft, and rotates at a fixed speed. When the rotor turns, it causes the field poles (the electromagnets) to move past the conductors mounted in the stator. This, in turn, causes electricity to flow and a voltage to develop at the generator output terminals."

Detailed explanation-2: -To produce electricity, a turbine generator set converts mechanical energy to electrical energy. In the cases of natural gas, coal, nuclear fission, biomass, petroleum, geothermal and solar thermal, the heat that is produced is used to create steam, which moves the blades of the turbine.

Detailed explanation-3: -The generator is connected to the turbine drive shaft. It has a moving part–the rotor–and a fixed part–the stator. The rotor’s outer surface is covered with electromagnets.

Detailed explanation-4: -Turbines catch the wind’s energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn.

Detailed explanation-5: -The steam spins a turbine, which is connected to a generator that produces electricity.
