• provides no path for current flow

The plastic covering is there to:

• Provide a conductor for electrical energy to flow.

• Provide an insulator so that electrical energy will not pass outside of the wires.

• Provide a conductor so that electrical energy can NOT flow

• Provide an insulator so that electrical energy can flow.

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

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

• The bulb doesn't light

• The bulb is dimmer

• The wires get hot

Choose the correct sentence.

• This circuit will work because it is an open circuit.

• This circuit will work because it is a closed circuit.
