ClassX Video Lessons Youtube Channel Next Generation Science Adding Batteries in Series to a Simple Circuit
Have you ever wondered what happens when you add more batteries to a simple circuit? Let’s find out together!
Imagine you have a simple circuit with two batteries connected in a line, which we call “in series.” When you close the switch, the electricity flows, and the motor starts to turn. This makes the fan spin, and you can feel the air blowing.
Now, let’s try adding two more batteries to the circuit. What do you think will happen? When we do this, the motor turns even faster, and the fan spins more quickly, blowing air even harder!
Adding more batteries in series increases the amount of energy, or voltage, that flows through the circuit. This extra energy makes the motor work harder, so the fan spins faster. It’s like giving the motor a little extra power boost!
Did you know that many devices, like remote-controlled cars and flashlights, use batteries in series to work better? Next time you use one, think about how the batteries are helping it run!
Now you know how adding more batteries in series can make a simple circuit work even better. Keep exploring and have fun with science!
Battery Hunt: Go on a scavenger hunt around your home to find devices that use batteries. With the help of an adult, carefully open the battery compartment of a flashlight or remote control to see how the batteries are arranged. Are they in series? Draw a picture of what you see and share it with your class.
Build Your Own Circuit: With adult supervision, use a small motor, a few wires, and some batteries to create your own simple circuit at home. Start with two batteries in series and observe how the motor runs. Then, add more batteries and see what changes. Write down your observations and think about why the motor behaves differently with more batteries.
Question Time: Imagine you have a toy car that runs on batteries. If you wanted it to go faster, what would you do? Discuss with a friend or family member how adding more batteries in series might help. Can you think of any other ways to make the car go faster?

Simple Circuits: Series Circuits
What happens when more batteries are added to a simple circuit in series? This simple circuit has two batteries connected in series. When the switch is closed, the motor turns and the fan operates. Observe what happens when we add two more batteries to the circuit. The motor turns faster, and the fan blows air more rapidly.
