As you continue to add lightbulbs in series, what happens?
The bulbs get brighter
The bulbs get dimmer
The bulbs remain the same brightness
The bulbs explode and shards of glass get everywhere
If one bulb goes out in a series circuit, the remaining bulbs...
also go out
get brighter
get dimmer
explode, leaving shards of glass everywhere
Current is measured in
Volts
Watts
Seconds
Amps
If the switch was opened, what would happen?
the ammeter would measure a current flowing
current would no longer flow, so everything would be off
the bulbs would stay on because they're connected to the cell
the bulbs would burn out and catch fire
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.
This is an example of a _______ circuit
open
series
parallel
switch
A parallel circuit
has only one path for current to travel
has more than one path for current to travel
does not allow electricity to travel through it
has magnets that cause electric current
When more light bulbs are added they all remain bright.
What is a Series Circuit?
A circuit with more than one path way for current to flow
A circuit with one path way with one switch.
An electric circuit with a single path for current to flow.
Two circuits with one path way for current to flow
What is Parallel Circuit?
A wire that has a battery and a switch.
A circuit that contains more than one path for current flow.
A circuit that contians one path for current flow
A circuit with a switch

What would happen if you added an extra bulb?
Nothing
The light bulb would get dimmer
The light bulb would get brighter
The circuit wouldn't work
