Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
- Statement I: Increasingly, photovoltaic panels are being used to supplement electrical energy from the power grid.
- Statement II: The compatibility of photovoltaic panels with the power grid is because they produce Direct Current (DC).
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect ✓ Correct
DStatement I is incorrect but Statement II is correct
Correct answer: (C) Statement I is correct but Statement II is incorrect — Statement I is correct but Statement II is incorrect, so that is the answer.
Explanation
★Statement I is correct but Statement II is incorrect, so that is the answer.
★Photovoltaic panels are increasingly used to add to grid electricity, so Statement I is correct.
★A solar panel generates direct current when sunlight falls on it.
★The power grid, however, runs on alternating current, not direct current.
★An inverter converts the panel's DC into AC to match the grid.
★So the panels are compatible because of this conversion, not because they produce DC, making Statement II wrong.
