1. Basic Electrical Circuits

2. Any arrangement of components that allow an electrical current to flow
Definition
Any arrangement of components that allow an electrical current to flow

3. There is only one path for the electrons to flow
A Basic Circuit
Battery
Source = Battery
Wire
Conductor = Wire
Lamp
Load = Lamp
Switch
Control = Switch
There is only one path for the electrons to flow

4. A Series Circuit Source = Battery Load = 2 Lamps Conductor = Wire
Control = Switch
Electrons can only flow along one path, and MUST go through each component before getting to the next one.
Switch

5. A Parallel Circuit Source = Battery Load = 3 Lamps 3 Lamps Battery
Conductor = Wire
Control = Switch
Switch
Wire
Two or more components are connected so that current can flow to one of them WITHOUT going through another

6. A Series-Parallel Circuit
A combination of components both in Series and in Parallel
