Compute current, voltage, resistance, and power, using Ohm's law and Watt's law.
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?
