Circuit Diagrams
•
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.
Using the proper symbols, draw a circuit diagram showing;
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 _______________ path.
•
Loads are connected in a chain, one after another in one __________________ loop.
•
When one load does not work, the whole chain of loads stops working because
____________________ cannot flow.
Series Circuits
Parallel Circuits
•
In a parallel circuit, electrons can flow through __________________________ path.
•
Loads are connected in ___________________
_____________________ that are
connected to the energy source.
•
When a load does not work in one branch, the loads in the other branches
____________________ to function because ______________________ can flow
through another __________________.
Example 1)
Draw a circuit diagram showing an electric cell, a switch,
and 3 lamps connected in series
Example 2)
Draw a circuit diagram showing a 2-cell battery with 3
lamps connected in parallel. Include a switch for
controlling each lamp.
