Computation requires an understanding of the mathematical and scientific concepts related to Watt’s law and power and should include
- defining the terms of the equation for Ohm's law and Watt's law:
- Ohm's law: V = IR; I = V/R; R = V/I
- Watt’s law: P = VI; I = P/V; V = P/I
- describing the basic scientific principle that if resistance to current flow stays the same and the voltage pressure increases, the current flow rate must also increase.
Process/Skill Questions:
- What is Watt’s law?
- What are the mathematical relationships of Watt’s law?
- How can Watt’s law be used to evaluate circuit characteristics?
- What are the units of measurement involved in Watt’s law, and what is their relationship to one another?
- How do Ohm’s law and Watt’s law relate to each other in the analysis of electronic circuits?
