Circuit Diagrams 13.1 Using the proper symbols, draw a circuit diagram showing: 1 cell 1 light bulb 1 open switch on the negative side of the bulb circuit diagram

Series Circuits 13.1 In a series circuit, electrons flow through only one path. Loads are connected in a chain, one after another in one continuous loop. When one load does not work, the whole chain of loads stops working because electrons cannot flow. series circuit

Series Circuits 13.1 series circuit

Parallel Circuits 13.1 In a parallel circuit, electrons can flow through more than one path. Loads are connected in different branches that are connected to the energy source. When a load does not work in one branch, the loads in the other branches continue to function because electrons can flow through another path. parallel circuit

Parallel Circuits 13.1 parallel circuit

Ex 1) Draw a circuit diagram showing an electric cell, a switch, and 3 lamps connected in series

Ex 2) Draw a circuit diagram showing a 2-cell battery with 3 lamps connected in parallel. Include a switch for controlling each lamp.
