The picture shows an electrical circuit. This circuit is a series circuit because:
It has 3 light bulbs.
The same current flows through all three light bulbs.
It uses a single battery.
The electrical current is divided between the three light bulbs.
What kind of circuit is this?
series
parallel
This circuit has more than one loop. When one light goes out, the others stay on.
closed circuit
series circuit
parallel circuit
open circuit
One of the advantages of _________ circuits is that they ensure all components in the circuit have the same voltage
as the source.For instance, all bulbs in a string of lights have the same brightness.
open
multiple

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.
parallel
series
opened
closed
all bulbs are lit equally the two top bulbs are brighter the single lower bulb is brighter the single bulb does not light and the other two are dim
all bulbs are lit equally
the two top bulbs are brighter
the single lower bulb is brighter
the single bulb does not light and the other two are dim
when the switch is closed.....
both bulbs TURN ON
both bulbs STAY ON
both bulbs TURN OFF
both bulbs STAY OFF
This type of circuit has multiple paths for the current to flow. If one component fails, the current can still flow through other paths.
