Question
Describe the difference in voltage output when cells are connected in series compared to when they are connected in parallel.
Answer
When cells are connected in series, the total voltage is the sum of the individual cell voltages. In contrast, when cells are connected in parallel, the voltage remains the same as that of a single cell, but the current capacity increases.
Explanation
This answer highlights the differences in voltage output based on the connection type, testing the student's understanding of electrical circuits and the behavior of cells in different configurations.
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.
