1.
A circuit where electricity can flow because all the connections are complete. Think of a light switch in the "on" position—electricity flows, and the light turns on.
2.
A circuit that has a break, stopping the flow of electricity. If a wire is disconnected or a switch is off, the circuit is open, and the device won’t work.
3.
Electricity flows in one direction only.
4.
Electricity changes direction many times per second.
5.
A tiny particle that carries electric charge. When electrons move through a wire, they create an electric current.
6.
Measures how much electricity is flowing in a circuit. Think of it like the amount of water flowing through a hose.
7.
Measures resistance, or how hard it is for electricity to flow. Think of it like a narrow pipe slowing down water.
8.
Measures how much energy is used by an electrical device. More power means a device uses more energy.
