The image below shows the basic construction of a hydroelectric dam. A student claims that the type of energy transformation that occurs in this system is mechanical to electrical.
Which of the following statements would BEST support the student's claim?
A. Electricity must move to travel through power lines and reach people’s homes.
B. The turbine must turn for electricity to flow from the generator to the power lines.
C. Water must flow from a higher place to a lower one for electricity to be created.
D. The electricity flowing through the power lines has enough energy to move objects.
B. The turbine must turn for electricity to flow from the generator to the power lines.
This statement directly relates to the energy transformation occurring in a hydroelectric dam, as mechanical energy from the flowing water turning the turbine is converted into electrical energy.
