Question

the power of water
if you’ve ever seen a river chuckling as it
races by, like it’s carrying feathers instead
of boats, you know how powerful moving
water is. over the years, people have
learned how to harness the power of
water not only for recreation, but also for
energy. hydroelectricity is made by
taking the energy of running water and
changing it into a form of energy that we
can use. hydroelectric plants create
nearly one - fifth of the world’s electricity.
this makes the enormous power of water
one of the most important energy
sources on earth.
based on the passage and the diagram
on page 3, which parts of the hydroelectric
system are most directly involved in
sending electricity to outside the power
plant? drag two answers to the box.
two parts most directly involved in sending electricity

the penstock the turbine
the power lines the generator
the dam

Explanation:

1. The generator is the component that converts the mechanical energy from the turbine into electrical energy, which is the critical step to create the electricity that will be sent out.
2. Power lines are the direct infrastructure that transports the generated electricity from the power plant to external locations where it is used.

Other components like the dam, penstock, and turbine are involved in capturing and transferring the water's mechanical energy, but do not directly send electricity outside the plant.

Answer:

• the generator
• the power lines
