Elementary charge

An elementary charge is like the building block of electricity. Imagine you have a jar of toy building blocks with different shapes and sizes. But instead of physical blocks, electric charges come in one size and shape only - the elementary charge. It's like having a jar of small balls that are all the same size and shape.

Electricity is made up of tiny particles called electrons, and one electron has one elementary charge. Just like how every block in your jar would be made of the same material, every electron has the same amount of elementary charge. It's like all the balls in your jar are made of the same material and are all the same size.

Scientists use the symbol 'e' to represent elementary charge. Because these charges are so small, they are measured in a unit called Coulombs. One Coulomb is a really big group of elementary charges all together. It's like saying that one jar of blocks is a really big group of individual blocks.

When we talk about electricity, we are really talking about the movement of electrons and their elementary charges. When electrons move from one place to another, they carry their elementary charge with them. This movement creates an electrical current, which is like a river of electricity flowing through a wire.

So, in summary, elementary charges are like the building blocks of electricity. They are tiny particles that make up electrons, and every electron has the same amount of elementary charge. When electrons move, they create an electric current, which is how we get electricity to power our homes and devices.
