• # question_answer A wind powered generator converts wind energy into electrical energy. Assume that the generator converts a fixed fraction of wind energy intercepted by its blades into electrical energy. For wind speed v, the electrical power output will be proportional to A) $v$ B) ${{v}^{2}}$ C) ${{v}^{3}}$ D) ${{v}^{4}}$

Correct Answer: C

Solution :

we have got $P=\frac{1}{2}\rho A{{v}^{3}}t$ $\therefore \,\,\,\,\,\,P\propto {{v}^{3}}$
