Question 50

In a hydroelectric power station, energy is transferred through a series of processes:

falling water→turns turbine→turns generator→transformer \text{falling water} \rightarrow \text{turns turbine} \rightarrow \text{turns generator} \rightarrow \text{transformer} falling water→turns turbine→turns generator→transformer

What are the pathways for the transfer of energy from the falling water to the turbine, and from the generator to the transformer, respectively?

A

mechanical working, mechanical working

B

electrical working, mechanical working

C

mechanical working, electrical working

D

heating by particles, electrical working
