What is electricity?
an object that electrons do not flow through
energy created by moving charged particles
when two objects repel each other
a circuit that has only one path for electricity to flow
This picture shows a circuit that is
closed
open
an insulator
static electricity
A parallel circuit has more than one path for electricity to flow
true
false
Imagine you are creating a circuit. It works and the light bulb turns on. Then you add a piece of plastic to the circuit, and the light bulb does not turn on. We can infer that the plastic is
an insulator
a conductor
an electron
static electricity
If the light bulb turns ON in a circuit, that means the circuit is
open
closed
If you hear thunder, lightning is close enough to strike you.
