A closed path that allows the flow of electricity is called a...
path
current
circuit
generator
____________ allows electricity to flow through it
A conductor
An insulator
A magnet
A balloon
____________ stops the flow of electricity.
A conductor
An insulator
A magnet
A wire
Two batteries in a circuit make the lights in the circuit brighter than one battery.
true
false
In a parallel circuit the current
makes one circle
stays in one path
splits and goes through multiple paths
does not flow
An example of a parallel circuit is
the wiring in a house
a flashlight
a single circular path
a battery connected to one lightbulb
The flow of electricity requires a
complete path
incomplete path
insulated current
light bulb
In a series circuit the current
goes through two or more loops
stays in one path
splits and goes through multiple paths
does not flow
An example of a series circuit is
the wiring in a house
a flashlight
a cell phone
the lights in a school
