When two identical solar cells are connected in series, how do their potential differences and currents combine?

1. In series, the potential differences of the cells add together. 2. The current from the combination equals the current of one cell, so currents do not add. 3. Therefore voltages add while current stays the same. 4. Option B describes the parallel case, where currents add, so it is the trap and is ruled out. 5. Option C wrongly adds both, ignoring that current is unchanged in series. 6. So voltages add and current stays the same. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology Part 2, Ch 5 "Towards Green Energy", p.66_
