Did You Know?
Some batteries can last a long time!
How Power Flows
The power goes out from the cathode.
What Makes a Cathode
A cathode is made of special stuff.
What cathode Does
The cathode sends out power.
It helps toys and lights work.
It is part of a battery.
It has a + sign on it.
It is very small but strong.
It helps us use power every day.
More About cathode
The cathode is a small part of a battery. It helps make power go out. Without it, the battery would not work. It is very important for many things we use.
We see cathodes in toys, lights, and more. They help us play and see in the dark. When we change batteries, we see the + sign on the cathode.
In the future, we may have new kinds of batteries. They might use different materials for cathodes. This can help us save energy and help the Earth.
