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
What is a circuit that only has ONE path for electricity to flow?
series circuit
closed circuit
parallel circuit
light bulb
What is a circuit with several paths for electricity to flow?
conductor
series circuit
parallel circuit
open circuit
What type of circuit is shown?
Parallel
Series
What is the power source in this circuit?
Bulb
Switch
Wire
Battery
What is the function of a resistor?
Stop current flow
Limit current flow
Limit voltage
To light up
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
To complete the circuit, a wire should be placed from —
Why is 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
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 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
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
True or False: A steel nail would allow electricity to flow through it because steel is a great conductor of electricity.
True
False
