What happens in a circuit when we change the components?

In this lesson, we will be learning about voltmeters and ammeters. We will then investigate what happens when we change the number of cells and lamps in a circuit. We will be writing predictions and conclusions in this lesson. You will need a pencil, a piece of paper and a ruler.
