My First Circuit

Series Circuit

When components are in a series the electrical current flows through both one after another. In this example, both buttons must be pressed at the same time for the LED to light.

Parallel Circuit

When components are parallel the electrical current is split between them. In this example, if either button is pressed the LED will light up.
