ELEC 243

Prerequisites

This is list of skills you should have to take ELEC 243. Most of these are covered in first year mathematics and physics classes, in particular, manipulating complex numbers, using simple derivatives and integrals, and familiarity with electrical quantities and basic circuits. The material is covered in Chapters 26, 27, 32, and 33 of the PHYS 102 text (Physics for Scientists and Engineers, Fishbane, Gasiorowicz, and Thornton), and in Chapters 1–3 of the course text.

Prerequisite Learning Objectives

  1. Solve a low-order system of linear algebraic equations.
  2. Differentiate and integrate simple expressions, and solve a simple, first order linear differential equation.
  3. Sketch a graph of an elementary function of time, and label important points, such as a sinusoid, exponential, or log.
  4. Perform algebraic manipulations and combinations of complex numbers; transform complex numbers from Cartesian coordinate form to polar form, and graph them in the complex plane.
  5. Define the primary electrical quantities, along with their common units and symbols, such as current, voltage, resistance, inductance, and capacitance.
  6. Identify the principal elements of electrical circuits, such as nodes, loops, meshes, and branches.
  7. Define the voltage-current (V-I) characteristics of the passive, ideal, linear circuit elements: resistors, capacitors, inductors, and sources.
  8. Use Ohm’s Law to calculate dc currents and/or voltages in simple resistor circuits, such as a voltage divider or current divider.
  9. Calculate the equivalent resistance, capacitance, or inductance of elements in series, parallel, or series-parallel combinations.
  10. Calculate the dc power dissipated by a resistor.
