A solar photovoltaic cell is special because it generates electrical energy:
ADirectly from sunlight, no generator
BBy burning a small amount of coal
CBy spinning a magnet inside a coil
DBy boiling water into hot steam
Answer & Solution
Correct answer: A. Directly from sunlight, no generator
1. In all other plants, a generator works by electromagnetic induction.
2. A photovoltaic cell instead converts solar radiation directly into electricity.
3. This needs no generator and no induction, so option A is correct.
4. Spinning a magnet in a coil (option C) describes a generator, which the cell does not use, so it is ruled out.
