• A circuit where components are wired in such a way that there are multiple paths for electricity to flow through.

What is a schematic diagram?

• A representation of a circuit that uses pictures to show how components in a circuit are connected.

• A circuit where components are wired one after the other, forming a single path for current to flow through.

• A representation of a circuit that uses graphical symbols to represent each component.
