What is a proton?
A subatomic particle in the nucleus of an atom with a positive charge.
|
What are electrons?
The movement of this subatomic particle creates electric current.
|
What is a battery.
A source of power commonly used in portable electronic devices.
|
What is voltage?

|
What is a neutron?
A subatomic particle in the nucleus of an atom with a neutral charge.
|
What is a conductor?
A material that electrical current can move easily and quickly.
|
What is a wire.
Where electric current travels.
|
What is an electric current?
A stream of charged particles, such as electrons or ions, moving through an electrical conductor.

What is an insulator?
A material that does not let electrons move well.
|
What is a load?
A device that consumes electricity.
|
What is resistance?
Measure of the opposition to current flow in an electrical circuit.
