On the left is a circuit with a bulb that is illuminated. On the right is a circuit with two of the same bulbs, but no battery. What would be the brightness of the two bulbs if you moved the battery over to that circuit?
they would be brighter than the one bulb is now
they would be dimmer than the one bulb is now
they would be the same brightness as the one bulb now.
What does a switch do in an electrical circuit?
it creates more power
it provides a convenient place to open and close the circuit
it always makes the bulb brighter
What are the blue "dots" that are flowing through a circuit to make a bulb light up?
protons
neutrons
electrons
One the left is a circuit with a lit light bulb. On the right is a similar circuit, but with 2 spaces for batteries. What would happen to the brightness of the bulb if two of the same battery were placed in the spaces?
The bulb would be brighter.
The bulb would be dimmer.
The bulb would be the same brightness.
Pictured here is a series circuit. What would happen to the bulbs if the switch (highlighted in yellow) were to be opened?
the left bulb would go out
the right bulb would go out
both bulbs would go out
neither bulbs would go out
Pictured is a parallel circuit, with two switches at the top. What would happen if the switch highlighted in yellow were to be opened?
