Activity (Hands-On)Grades 9 - 12
Ohm's Law 2
Students continue their investigation of Ohm's law.
In this extension to the Ohm's Law I activity, students observe just how much time it takes to use up the "juice" in a battery, and if it is better to use batteries in series or parallel. This extension is suitable as a teacher demonstration and may be started before students begin work on the Ohm's Law I activity.
Ohm's law is the basis of all electrical systems. Electrical engineers use this equation to guide the design of electrical systems. Students need a strong foundation in Ohm's law while designing circuits on their own.
Application of the following:
- Ohm's law
- series/parallel circuits (ways to connect them and have an effect on V and I)
- circuit components
- power
- devices that can be used to measure voltage and current
