Question

What are the main energy changes in a hydroelectric power station?
a) electrical------->kinetic------->heat
b) potential------->kinetic------->electrical
c) kinetic------->light ------->electrical
d) heat------->electrical------->kinetic

anonymous · Answer

beta is correct
water is hydroelectric power station is stored at a higher level and have potential energy due to height,
when it is dropped from this height over the propellers of turbine P.E is converted into rotational K.E, this mechanical energy is converted into
electrical energy by generators
