• 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

Using the proper symbols, draw a circuit diagram showing:

• 1 cell• 1 light bulb • 1 open switch on the negative side of the bulb

Page 7: 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

• 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.

• 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.
