When the switch is closed in a simple series circuit, why does the bulb light?
A
The switch produces electricity
B
Opening the switch breaks the circuit
C
Closing the switch breaks the circuit
Next
Why does the bulb go out when you open the switch in a simple series circuit?
A
The battery goes flat
B
Opening the switch breaks the circuit
C
Too much electricity flows through the bulb
Next
If a simple series circuit has one 1.5V battery and one bulb, what would happen if the 1.5V battery was replaced with a 3V battery?
A
The bulb would get brighter
B
The bulb will get dimmer
C
The bulb would stay the same
Next
Circuit A has one 1.5V battery and one bulb. Circuit B has a 3V battery and two bulbs. On which circuit would the bulbs be brightest?
A
Both would have similar levels of brightness
B
Circuit A
C
Circuit B
Next
If a 1.5V battery and a 3V battery are both connected across a simple series circuit, why might the bulb flash and go out?
A
There isn’t enough electricity flowing through the circuit
B
The batteries are flat
C
To much electricity flows through the bulb’s filament so
the bulb blows
Next
If you changed straight thick wire to straight thin wire in a circuit, what would happen?
A

B
The bulbs would become brighter
C
The bulbs would become dimmer
Next
What would happen if the wire in a circuit was changed from straight thick wire to a longer coiled thick wire?
A
The bulbs would stay at the brightest level
B
The bulbs would become brighter
C
The bulbs would become dimmer
