Asolar cell is used to run a small fan. describe the energy transformation in a solar cell. a)it transforms heat into mechanical energy. b)it transforms heat into light energy. c)it transforms light energy into electrical energy. d)it transforms electrical energy into light energy.

The correct answer is
"c)it transforms light energy into electrical energy."

In fact, the solar cell collects the light from the Sun, which carries a certain amount of energy, and then this energy is converted to electrical energy, which is then used to run the small fun. So the initial energy carried by the light (photons) is converted into electrical energy.
