circuit | a path for energy to flow (circle) |
current | the movement of electrical evergy from one place to another |
electricity | a form of energy that can pass through wires made of special metal |
light | bulbs change electical energy to light wo we can see at night |
heat | coils change electrical energy to heat so we can be warm in winter, or cook our food |
conductor | allows electricity to flow |
insulator | does not allow electricity to flow |
electromagnet | electrical energy becomes a magnet to attract metal containing iron or steel |
