Electricty/EnergyVocabulary & Terms

Static Electricity•When you take off your wool hat, it rubs against your hair. •Electrons move from your hair to the hat. •A static charge builds up and now each of the hairs has the same positive charge. •Remember, things with the same charge repel each other. So the hairs try to get as far from each other as possible. The farthest they can get is by standing up and away from the others. And that is how static electricity causes a bad hair day!

Types of CircuitsOpen Circuits Closed Circuits

Series and Parallel Circuits•In a series circuit, both bulbs are connected in a row, with electricity passing first through one then the other. •In the parallel circuit, electricity passes through both bulbs at the same time. •A major advantage of parallel circuits is that if one bulb malfunctions, the other bulbs continue to function. •In a series circuit, when one bulb breaks, both bulbs stop working.
