HYDRO ELECTRIC POWER PLANTS

MULTIPLE CHOICE QUESTIONS

(MCQ) WITH ANSWERS

MCQ are very helpful in understanding a

topic. It also increases level of clarity. It is

then possible to apply the fundamentals in

real life applications. Hydro power plants

are established in hilly areas. Initial cost of

installation is high. But later operating

charges are small. Thus over number of

years, this method becomes economical.

Big and small hydro power plants are

found all over the world.
