Drawing circuits 

A circuit consists of electrical components that are connected to each other.

Circuit 

Electrical components are, for example, a voltage source, a lamp and a switch.

The wires connect these parts.

How would draw a lightbulb?

Series circuit

Circuits

Characteristics of a series connection

The amperage through each light is equal to

the amperage through the source.

The amount of voltage will be devided

Circuits

Features of a parallel circuit:

The current through the voltage source is the sum of

the currents through the lights.

The amount of voltage will not be devided
