# Define Ohm's law.

## Definition

Definition should include- providing the equation of Ohm’s law
- voltage (VE) is equal to current (I) multiplied by resistance (R)
- describing Ohm’s law, attributed to Georg S. Ohm, as a simple and useful tool for analyzing electric circuits.

## Process/Skill Questions

- What is Ohm’s law?
- What are the mathematical relationships of Ohm’s law?
- How can Ohm’s law be used to evaluate circuit characteristics?
- What are the units of measurement involved in Ohm’s law, and how do they relate to one another?
- In which circuit configurations do the basic principles of Ohm’s law not apply?
