fuel

Air

Burners

An induced voltage

• The generator uses motion to create a voltage (dynamo)
• Coil & magnet
• Magnet moves --> voltage changed
• Alternating voltage, also known as induced voltage

Dynamo 

• Magnet & coil
• Bicycle weel spins --> magnetic field changes in the coil --> voltage induced --> lamp goes on.
• Same as in a generator!

Dynamo 

• 1 revolution of the dynamo
• magneticfield switches 2x
• = so 1 period of the voltage-time graph.

You can generate an alternating voltage using a dynamo. This kind of alternating voltage is also known as an...........

What belongs where?

Burners

Turbine

Generator

Transformer

Condenser

A lot of heat is generated in this part, this heat is released and heats the water in the boiler.

Here, steam is used to create movement.

Induction is used to generate an alternating voltage.

Here the voltage is converted so that it can be distributed.
