1. In a simple series circuit, why does the bulb light when you close the switch?
A-Because the switch produces electricity
B-Because closing the switch completes the circuit
C-Because closing the switch breaks the circuit
. In a simple series circuit, why does the bulb go out when you open the switch?
A-Because the battery goes flat
Because opening the switch breaks the circuit
C-Because too much electricity flows through the bulb
Imagine a simple series circuit with one 1.5V battery and one bulb. When the 1.5V battery is replaced with a 3V battery ...
The bulb gets brighter
The bulb gets dimmer
C-the bulb stays at the same level of brightness
Imagine a circuit with a 1.5V battery and one bulb. Imagine a similar circuit with a 3V battery and two bulbs. Which has the brightest bulbs?
A-The circuit with a 1.5V battery and one bulb
B-The circuit with a 3V battery and two bulbs
C-The bulbs in both circuits are of similar brightness levels
Why might a bulb flash and go out when a 1.5V battery and a 3V battery are both connected across it in a simple series circuit?
A-There is not enough electricity flowing around the circuit
B-Too much electricity flows through the bulb's filament and the bulb blows
C-The batteries are flat
