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.
Old Christmas lights—if one bulb burns out, all the lights go out because the circuit is broken.
4.
The lights in your home are on a parallel circuit. If one light goes out, the others stay on.
5.
A string of modern Christmas lights—some bulbs may go out, but others stay on.
6.
Electricity flows in one direction only.
7.
Electricity changes direction many times per second.
8.
A tiny particle that carries electric charge. When electrons move through a wire, they create an electric current.
9.
Measures how much electricity is flowing in a circuit. Think of it like the amount of water flowing through a hose
10.
Measures resistance, or how hard it is for electricity to flow. Think of it like a narrow pipe slowing down water.
11.
Measures how much energy is used by an electrical device. More power means a device uses more energy.
