Did you ever wonder why it takes two batteries stacked together to run a flashlight or why your video game player takes four batteries? Why do they need to be put into these devices a certain way? This activity will allow you to explore how all this works by measuring the voltages across different numbers of batteries stacked together.
In this activity, you will
Measure the voltages of batteries as they are stacked together.
Compare the voltages of different types of stacked batteries.
Draw conclusions about batteries in electronic devices.
