Which part of an electric circuit provides the energy for the circuit?
wire
light builb
battery (voltage source)
switch
What particles flows through an electric circuit?
proton
neutron
electron
none of the above
Which statement is true about the picture?
The circuit will work because the switch is open.
The circuit won't work because the switch is open.
The circuit will work becasue electrons can flow through freely.
There is no break along this circuit pathway.
What type of circuit is shown?
series circuit
parallel circuit
broken circuit
force field circuit
What type of circuit is shown?
series circuit
parallel circuit
broken circuit
force field circuit
If I remove the middle light bulb, will the other two light bulbs work?
maybe?
Yes - this is a parallel circuit. The other light bulbs still have a direct pathway to the energy source.
No - you remove one lightbulb and the whole thing doesn't work.
Yes - this is a series circuit. The other light bulbs still have a direct pathway to the energy source.
If one of the lightbulbs is broken (meaning it won't light) will the other light bulb work?
Maybe?
Yes - this is a series circuit. Even though there is a break within the cirucit, electrons can flow freely.
No - this is a series circuit. The broken lightbulb leaves a break along the circuit not allowing electrons to flow freely, breaking the pathway from the lightbulb to the energy source.
I do not know.
Which items below would be needed to create an electromagnet?
a battery (power source)
a magnetic material (iron)
a light bulb
wire
Which circuit will light the bulb?
