wood
ceramic
plastic
When a switch is _________, the electric current can flow through the circuit.
open
closed
If a switch is ______, a light bulb will not light.
open
closed
A(n) ________ is formed when an electric current passes through an unbroken path of conductors.
battery
insulator
surge protector
circuit

circuit
What makes up an electric circuit?
Bulb and battery
Bulb, battery and switch
Bulb, battery and wire
Why is a battery important in an electrical circuit?
As a source of energy.
As a path for electricity to flow through.
As a connector to connect all parts of a circuit.
Look at the diagram. Why did the bulb not light up?
The bulb was fused.
The battery had not enough electric current to light up the bulb.
The switch was opened and prevented electric current from flowing through the circuit.
The diagram shows a complete circuit but the bulb did not light up. Why?
The plastic spoon is an insulator of electricity and prevented electric current from flowing through the circuit.
The plastic spoon is not connected properly and prevented electric current from flowing through the circuit.
The plastic spoon is a conductor of electricity and prevented electric current from flowing through the circuit.
State one advantage of bulbs arranged in parallel arrangement in a circuit.
When one bulb burns out the other can still light up.
Reduce the amount of electric current used for both bulbs.
Both bulbs in a parallel arrangement in circuit will share the electric current produced by the battery.
In order for electricity to flow through a circuit, the circuit must be a closed, complete:
Path, so that the electricity can make a complete circle.
Donut, because circuits get hungry.
Wire, made out of rubber.
Solar panel, because circuits only work with the sun.
The circuit on the left is not complete (the light is off) because:
the switch is closed
the switch is open
the battery is missing
the battery is in backwards
The circuit on the right is complete (the light is on) because:
the switch is closed
the switch is open
the battery is hot
the battery is red
How many light bulbs would be ON with this complete circuit?
1
3
2
4
How many light bulbs would be ON if the wire of this circuit was cut where the scissors are?
1
3
2
0
How many light bulbs would be ON if the wire of this circuit was cut where the scissors are?
1
3
2
0
What is missing from this circuit? Why would the light bulbs be off?
The battery, there is no power for the circuit to work.
The switch is open, so the circuit is broken.
The third light bulb, that is needed to complete the circuit.
The wires are not connected properly.
This rubber ducky would block the flow of electricity, because:
it is a conductor
it is an insulator
it is yellow
it completes the circuit
This steel paperclip would allow electricity to flow through it because:
it is a conductor
it is an insulator
it is friendly
it breaks the circuit
True or False: A wooden block would allow electricity to flow through it because wood is a great conductor of electricity.
True
False
Which one of these is a good conductor of electricity?
Paper Tube
Wax String
Metal Wire
Hot Tacos
