What is an electrical circuit?

• a whole bunch of wires

• a broken path that electric charges can flow

• a circuit board

• a complete, unbroken path through which electric charges flow

When a switch is open...

• the circuit is working and gives energy

• the circuit is broken and charges cannot flow

• the circuit is turning lights on

• I don't know...ask Ms. Cednick

What is voltage?

• the power in a machine

• how much electricity is in an object

• the difference in electric potential energy per charge.

• the electric current

Describe a series circuit.

• a circuit that has multiple branches

• a circuit that has one path

• a circuit that dead ends after a light bulb

Will the light bulbs light up in this image?

• Yes, both of them will

• Yes, but only the one on the right

• No, neither of them will

• Yes, but only the one on the left

Will this circuit light the bulbs?

• Yes, both will light up

• Yes, but only the one on the right

• Yes, but only one on the left

• No, neither of the bulbs will light up

Is this a working circuit?

• Yes

• No

• I'm not sure, I would need to test it myself.

Why electrical wiring usually are covered with a layer of plastic?

• To make it look pretty

• To help electricity flow along the wire

• To make it safe

• To add more energy

What needs to be done to this circuit so that the lamp lights up?

• Close the switch

• Add a source and close the switch

• Add another lamp

• Add another lamp and a switch

Why is electrical wiring usually made from copper?

• Because copper is shiny

• Because copper conducts electricity

• Because copper is not magnetic

• Because copper insulate electricity
