Simple d.c. Circuits

OBJECTIVES

In this chapter you will learn about:

  • Resistivities (specific resistance) of common materials
  • Types of resistors (fixed, variable, linear, non-linear, thermal, zero-ohm chip, networks, simulated, adjustable, lumped, distributed, integrated)
  • Ohm’s law and its application
  • Colour code for resistors
  • Temperature coefficient of resistance
  • The three types of electric circuits: series, parallel, and complex and solving for V, I and R
  • Fall of potential in series circuits and branching of current in parallel circuits
  • Voltage division and current division formulae
