Question
- A. 1.5 V
- B. 2.0 V
- C. 3.5 V
- D. 0.5 V
Answer
3.5 V
Explanation
The voltages of cells in series add: 1.5 V + 2.0 V = 3.5 V.
Common mistake
Misunderstanding Series Connections
Students often think that connecting cells in series increases the total current rather than the voltage.
Emphasize that connecting cells in series increases the voltage because the voltages of each cell add together, while the current remains the same.
