Lesson: The Electric Potential Difference Provided by Cells Science • Third Year of Preparatory School

Join Nagwa Classes

Attend live Science sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to calculate the potential difference provided by a cell based on the amount of work it does to separate charge.

Students will be able to

recognize that a potential difference is created by a separation of positive and negative charges,
recognize that by allowing charges to flow along conductors, a charge separation can be reduced to zero,
recall that the potential difference provided by a battery to a circuit is called its electromotive force,
use the formula .
