If you replace the paper clip with a plastic spoon, what happens?

• The bulb doesn't light

• The wires get hot

• The bulb is dimmer

• There is no change

A series circuit has ____ path(s) that the electric current can take.

• One

• Two

• Three

• Four

In a parallel circuit, if one connection is broken, all of the connections stop working.

• True

• False

An object through which electrons can easily flow is called a(n) ___________.

• Insulator

• Conductor

What kind of circuit is this?

• Series

• Parallel

this is the symbol for a _____?

• light

• battery

• switch

• wires

What kind of circuit is this?

• series

• parallel

The picture shows an electrical circuit. This circuit is a series circuit because:

• It has 3 light bulbs.

• It uses a single battery.

• The same current flows through all three light bulbs.

• The electrical current has more than one path to flow through

What is a Parallel circuit?

• Has only one path

• Allows energy to travel through easily

• Has only one light bulb

• Has more than one path

What is a switch's function in a circuit?

• to make the current hotter or colder

• turn on and off the flow of current

• the pathway that current flows

• to add more power to the circuit
