Cell Potential

Real World Example

Imagine trying to decide whether to wear a jacket when the weather feels unpredictable—some parts of the day are warm while others are chilly. This decision-making process is similar to determining the voltage between two half-cells in a battery, where one side may have a higher potential than the other. Just as you gauge the temperature difference to decide if you need a jacket, the voltage between two half-cells measures the difference in electrical potential, indicating how much energy can be harnessed from the battery to do work, much like how the temperature difference influences your comfort level.
