Dielectric

Imagine you are at a party with lots of people. If you try to walk through a crowd of people, it can be very difficult because they are all in the way. This is kind of like what happens to electric charges when they try to pass through a material that doesn't let electricity flow very easily - this is called a dielectric.

Now suppose you have a toy car with a remote control. If you want to make the car go left, you press the button on the remote that makes the car turn left. The toy car goes in the direction you want it to because the remote control sends a signal (like a message) to the car that tells it what to do.

Similarly, imagine that there are electric charges (like little bits of electricity) that you want to move from one place to another, but you need to send them through a dielectric material. If you try to send the charges directly through the dielectric, it's like trying to walk through a crowd of people - they get in the way and the charges can't move very easily.

But, just like with the toy car, you can use something called a capacitor to help you get the charges through the dielectric. A capacitor is kind of like a storage container for electric charges - it can hold on to them until they are ready to go.

So if you want to move electric charges through a dielectric, you can use a capacitor to store them up, and then release them all at once to get them to move through the dielectric. This is one way that dielectrics are used in electrical circuits, to help control and manipulate the movement of electric charges.
