Which variable in Ohm’s law is like friction that slows down the flow of electrons?
resistance
current
voltage
Which variable in Ohm’s law is responsible for pushing/forcing the electrons to move?
resistance
current

The circuit shown is a parallel circuit.
True
False
Which bulb will be the brightest?
Bulb A
Bulb B
Bulb C
They will all be the same
If all of the batteries have the same voltage, which circuit will have the dimmest (least bright) bulbs?
LEFT
MIDDLE
RIGHT
if they have the same voltage they will all be the same brightness.
Which light bulb is the brightest?
Bulb A
Bulb B
Bulb C
They are all the same
Starting with all bulbs on, what would happen if bulb A burned out?
Bulb B would also go out and bulb C would stay on
Bulb C would also go out and bulb B would stay on
Both bulb B and bulb C would go out
Both bulb B and bulb C would stay on
Starting with all bulbs on, what would happen if bulb B burned out?
Bulb A would turns off and bulb C would stay on
Bulb C would turns off and bulb A would stay on
Both bulb A and bulb C would turn off
Both bulb A and bulb C would turn off
What would happen if you closed the switch (meaning you connected it)?
Bulb A would turn off, but the others would stay on
Bulbs B and C would turn off and bulb A would stay on
All bulbs would turn off
All bulbs would stay on
