Which energy conversion takes place when a solar cell is used to light a street lamp? A.

solar energy → light energy

B.

solar energy → electric energy → light and heat energy

C.

solar energy → light and heat energy

D.

heat energy → light energy

E.

heat energy → light energy → electric energy

B. solar energy → electric energy → light and heat energy

Explanation:

The solar energy received from the solar rays is transformed into electrical energy, through a photovoltaic process that is part of the solar panel and other elements. Then the electric energy generates currents that pass through the electrical circuit and this transformation generates light in electric bulbs. Since energy conversion processes are never 100% efficient for the electric energy in the bulb is transformed into heat, for that reason the electric bulb emits part of its energy in the form of light and heat.
