Circuits Review

What is a Series Circuit?

• A circuit with more than one path way for current to flow

• A circuit with one path way with one switch.

• An electric circuit with a single path for current to flow.

• Two circuits with one path way for current to flow

What is a Conductor?

• A Parallel circuit

• A material that allows heat and electricity to flow through it

• The pathway through which electric current (electron) flows.

• A series current

What is an Insulator?

• A material that allows heat and electricity to flow through it

• The pathway through which electric current (electron) flows.

• A pathway that prevents electric current from flowing freely or stops the flow - light is off!

• A material that stops heat and electric current from flowing

What is an example of an Insulator?
