प्रश्न
Conceptual question.
Does a solar cell always maintain the potential across its terminals constant? Discuss
उत्तर
The electro-chemical process inside a battery provides electrons at the negative terminal and draws electrons from the positive terminal to maintain the current being drawn. By providing energy to the electrons, the cell is capable of maintaining an electric potential difference across the two ends of the external circuit.
