Question
Total potential difference across the combination of three cells becomes maximum when?
Correct Answer
Option B is the correct answer.
Detailed Explanation
When identical cells (or voltage sources) are connected in series, their individual electromotive forces (EMFs) add up. This configuration maximizes the total potential difference (voltage) across the combination. Connecting cells in parallel increases the current capacity but keeps the total voltage equal to that of a single cell (assuming identical cells). Other combinations would yield a lower total voltage than connecting all cells in series.
Hint
Consider how voltages add up in series circuits versus parallel circuits.
