let’s imagine our conductor is like a big, round, squishy playdough ball. 🟢 Now, pretend that little bugs are living on and inside this playdough ball. These bugs don’t like being inside the ball because it’s squishy and they push each other away (like similar charges). The bugs are like the charges in our conductor.
So, what do these bugs do? They crawl out to the surface of the playdough ball where they can spread out and have more space without pushing against each other.
That’s why we say the charges are on the surface of the conductor.
