When all parts of the circuit are connected it is a ______ circuit. 

• open
• closed

What is a switch's function in a circuit?

• to make the current hotter or colder
• turn on and off the flow of electrical current
• the pathway that electrical current flows
• to add more power to the circuit

A complete electric circuit that allows electrons to flow along an uninterrupted path is called a/n ___________________.
