Posters explaining simple circuits.
This resource has two posters in the download. One with a colored background and one with a white background to save ink.
Information on poster includes:
The electrical energy in a circuit comes from a battery. Positive current comes from the + end of the battery and flows through the wire to the light bulb. The light bulb changes the electric energy to heat and light. Once the current leaves the bulb it travels back to the battery. The positive current flows from + to – and the negative current flows from – to +. The on/off switch can stop the flow of electricity, so the light can be turned off.
