CHAPTER OBJECTIVES
• To introduce the concepts of electrostatic
potential difference, voltage and electro -
motive 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 the 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 ...
