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.
