Terminology and Units of Measurement


Description

Introduction to the various terminologies and the units of measurement used in the study of electricity

Learning Outcome:

Upon the completion of this module, you will understand

  1. Describe how the basic "building blocks"of matter—elements, compounds, molecules, atoms—are related to each other
  2. Explain how atomic structure is related to the study of electricity
  3. Define the coulomb, volt, ampere, and ohm
