Question

Which is the correct order of events at a power plant?

Question 9 options:

A)

Coal burned -> Heats water -> Creates Steam -> Turns a turbine


B)

Turbine turns -> Heats water -> Creates Steam -> Electricity travels down the lines


C)

Coal burned -> Transformer changes voltage -> Heats water -> Creates Steam


D)

Heated water -> Creates Steam -> Turns a turbine -> Burns coal

Answer 1

The correct answer is A.

A power station works on the principle of boiling water to create steam, which turns a turbine, generating a potential difference in a transformer with the magnets. The transformer is connected to a circuit, which hence induces a current, generating power.

Answer 2

The correct answer to the question is A.
This is because each prior step is needed for the next step to happen.
