# CTE Resource Center - Verso - Electronics Systems I Task 1258221487

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

## Definition

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?
