____ means a flow of electric charges.
What is electric circuit
100
What is the energy source for an electric charge?
What is the battery
100
Can a series circuit have more than one device? What happens if you remove a device in a series circuit?
What is yes; all the devices stop working because the circuit is no longer complete and current can't flow.
100
How is a parallel circuit different from a series circuit?
What is it has more than one path that the current can flow; if one path is damaged, electricity can flow along the other path.
100
If one burned-out bulb causes all the lights to fail in a circuit, what might you conclude?
What is It is a series circuit
200
_____ is an electric circuit with only one path for current.
What is a series circuit
200
Energy is changed to light an heat by the what?
What is the bulb
200
How does the amount of current that passes through each device in a series circuit compare?
What is the same amount of current passes through each device
200
In a parallel circuit, what effect does removing one device have on the other deceive?
What is it has no effect. The other devices still work.
200
A students added another light to an electrical circuit and all the lights became dimmer in the circuit. What is most likely the cause of the dimmer lights?
What is the circuit is a series circuit
300
____ is a flaw in a circuit that allows a large current to flow through where it isn't wanted.
What is a short circuit
300
What causes electric charges to flow (2)?
What is when they have a path to follow and a source of energy
300
What causes the devices in a series circuit to turn off?
What is a break in the circuit
300
What are devices in schools and homes plugged into sockets rather than being all wired together?
What is so they can be turned on and off separately.
300
What causes the filament in a light bulb to glow?
What is high resistance
400
_____ is how much material opposes the flow of electric current
What is resistance
400
If you connect a light bulb in the middle of the wire that connects the two ends of the battery, would it light?
What is yes, because the circuit is an unbroken path.
400
Why aren't all lamps and devices in homes wired in a series circuit?
What is if one goes out or is unplugged, they all go out
400
Does adding a light bulb to a parallel circuit cause it to go dimmer?
What is NO! it only does this with a series circuit!
400
What do the circles represent in an electrical circuit?
What is light bulbs
500
____ is an electric circuit with two or more paths for current
What is parallel circuit
500
How is the flow of water in a fountain like the path electricity follows in a circuit (2)?
What is both are continuous and unbroken; both are circular paths.
500
When you press the switch on a lamp, the light goes off or on. What does the switch do to make this happen?
What is it completes the circuit to make the lamp light; it opens the circuit to make the lamp turn off.
500
A student says that a series circuit can light only one bulb but a parallel circuit can light two. Was the student correct?
What is NO. Either kind of circuit can light two or more bulbs. The difference isn't in how many bulbs it can light, but in how bright the bulbs will be and what happens when one bulb burns out.
