Electricity Flowing in a Circuit

Electricity flows through circuits in the same way as water flows through pipes. Water only flows where the pipes are properly connected. Likewise, electricity will only flow where the components and wires are properly connected.

Notice also that electricity will only flow in a "complete circuit". Electricity must come from a source, and must go to a ground.

Resistors: Resisting current

Resistors are said to "resist current".
