Question

which of these shows a transformation from mechanical energy into electrical energy? a a fan blowing air b a wind turbine generating power c a lamp lighting a room d a microwave heating food

Explanation:

A fan blowing air converts electrical energy to mechanical energy. A lamp lighting a room converts electrical energy to light energy. A microwave heating food converts electrical energy to electromagnetic (microwave) energy which is then converted to thermal energy in the food. A wind - turbine generating power uses the mechanical energy of the wind (kinetic energy of moving air) to turn the turbine and generate electrical energy through electromagnetic induction.

Answer:

B. A wind turbine generating power
