This Power Lines interactive also includes:
How does electricity travel through power lines? The simulation demonstrates the how changes in voltage and resistance are related to the distance between power polls and the thickness of the cable. Scholars control three variables in order to discover how to enable the least — or greatest amount of resistance.
- Ask the local electric provider to have someone come speak to your class; most have an educator on staff
- Requires a free CK-12 account to access the interactive
- Assumes prior knowledge of voltage, current, and interpreting graphs
