• A battery

• A light bulb

this is the symbol for a _____?

• switch
• light 
• battery
• wires

This circuit is _________.

• open
• parallel
• closed
• The cutest little circuit evah!

The picture shows an electrical circuit.  This circuit is a series circuit because: 

• it has 3 light bulbs.
• the same current flows through all three light bulbs.
• it uses a single battery.
• the electrical current has more than one path to flow through

This circuit won't work. What essential part is missing from this circuit?

• resistance
• source of electric current
• conductor
• ammeter

Will the light bulb in this circuit light and why/why not?

• yes, because it has two batteries
• no, because the switch is open
• yes, because it is in a circuit
• no, because the bulb is burned out

Which light will be brighter and why?

• Bulb A because its circuit is closed
• Bulb B because its circuit is closed
• Bulb B because it has more volts
• Bulb A because it has less volts

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

• open
• closed
