If a circuit is connected and electricity is flowing through it, is the circuit open or closed?

What will happen to the power source (battery) if the circuit is shorted? (you may select more than one answer)

Name three types of power sources you can use.

If a circuit has a 9V battery and a total resistance of 180 ohms, how much current will be flowing through it?

What is the purpose of a capacitor?

If you have a 12V motor and a cell phone that can only withstand 5V, what type of voltage regulator will you need?

If you removed a lamp from a parallel circuit that had three paths, what would happen to the other two lamps?

How can understanding short circuits assist us in the future when dealing with electrical circuits?
