Circuit Diagrams An electric circuit can be represented

Circuit Diagrams • An electric circuit can be represented using a diagram. • Each part of the circuit is represented with a symbol. • By reading a circuit diagram, it is possible to determine how the circuit works and how to repair it when it does not function properly. 13. 1 circuit diagram

Circuit Diagrams 13. 1 Using the proper symbols, draw a circuit diagram showing: circuit diagram • 1 cell • 1 light bulb • 1 open switch on the negative side of the bulb

Series Circuits • 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. 13. 1 series circuit

Series Circuits 13. 1 series circuit

Parallel Circuits • 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. 13. 1 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.
