Question 119

The flow diagram shows the transfer of energy in a hydroelectric power plant:

falling water→rotates turbine→rotates generator→transmission lines \text{falling water} \rightarrow \text{rotates turbine} \rightarrow \text{rotates generator} \rightarrow \text{transmission lines} falling water→rotates turbine→rotates generator→transmission lines

What are the processes for the transfer of energy between the turbine and the generator, and between the generator and the transmission lines?

A

Turbine to generator: electrical working; Generator to transmission lines: mechanical working

B

Turbine to generator: mechanical working; Generator to transmission lines: electrical working

C

Turbine to generator: mechanical working; Generator to transmission lines: heating by thermal conduction

D

Turbine to generator: heating by thermal conduction; Generator to transmission lines: electrical working
