In this lesson, we will learn how to calculate the total e.m.f. of a set of cells that are connected in parallel.

Students will be able to

Q1:

The diagram shows three cells connected in parallel. What is the total emf provided by the cells?

Q2:

Four identical cells are connected in parallel. Each cell provides an emf of 3 V. What is the total emf provided by the cells if they are all aligned in the same direction?

Q3:

Nine identical cells are connected in parallel and are all aligned in the same direction. The total emf provided by the cells is 18. What is the emf provided by one cell?
