Electric Current & Potential Difference Knowledge
This page provides favorite resources for teaching about electric current,
potential difference and voltage. Voltage can be thought of as the water
pressure that moves electrons through a circuit. The further the water falls,
the greater the force. The greater potential difference (the falling of
the electrons), the greater the voltage measurement and the more work
electricity can do.

- When you arrive at the National Science Teachers Association site (NSTA)
www.scilinks.org, you will need to type
in the code SFEM18 to reach their special resources for teaching about
electric current and potential difference. At the Log-in prompt, click the
tiny black pull-down menu and select Guest, which will automatically enter a
username and password. Next click the Submit button. When the
input box appears, enter the SciLinks code of SFEM18. By the way, this is a
fabulous site to explore and membership in NSTA is highly recommended so as to
have access to additional resources.
