Chapter 1

Circuit Variables and Circuit Elements

CHAPTER OBJECTIVES
  • To introduce the concepts of electrostatic potential difference, voltage and electromotive force.
  • To introduce the concepts of ‘current density’ and ‘current intensity’ and to explain the conduction process.
  • To explain the ‘quasi-static’ approximation involved in circuit theory.
  • To explain the need for and role of quasi-static charge distributions over electrical devices.
  • To define and explain various idealized two-terminal element models in use in Circuit Theory.
  • To explain passive sign convention for two-terminal elements.
  • To relate power and energy in a two-terminal element to its terminal voltage and current variables.
  • To explain what is meant by ...
