Troubleshooting a Simple Circuit

Check whether the battery or power source

is working.

If there is more than one battery, are the
negative and positive terminals connected

properly?

Look closely at the wires and connections.

Are the wires connected properly to the

battery and the lightbulb (or other device)?

Is the switch turned on or off?

Does the circuit have a conductor or

insulator in the pathway?

Check the power source

Look at the connections

Examine the components

13

Electric Circuit

a path through
which
electrical
energy can
flow

14

Open Circuit

When electricity
does not flow
because there is not
a complete path for
electricity to flow
through

15

Closed Circuit

When electricity
flows in a
complete path
and can provide
power to items

16

Switch

A device used
to open and
close an
electric circuit

17

The circuit below does NOT work.

Which procedure would most likely allow the bulbs to light?

A.

Open the switch and then connect the two wires that are attached to the wood block.

B.

Switch the positions of the two wires that are connected to the battery and then open the switch.

C.

Move the switch closer in the circuit to the battery.

D.

Connect the two wires that are attached to the wood block.

Look at the examples of circuits below.

Which statement correctly describes the circuits?

A.

Circuit B is an open circuit that allows electricity to pass through.

B.

Circuit A is a closed circuit that allows electricity to pass through.

C.

Circuit B is a closed circuit that electricity cannot pass through.

D.

Circuit A and B are both open circuits that electricity cannot pass through.

DOL: Given scenarios,
SW correctly
troubleshoot
incomplete circuits
and describe how
electrical energy
travels in a closed
path in at least 4 of 5
questions.
