Electrical Engineering - Further AC Theory

Requirements

  • A basic understanding of AC Theory..
  • An understanding of Ohm’s Law..
  • A basic understanding of trigonometry..

In this course you will expand your knowledge and confidence working with AC values. Complex numbers will be introduced, and used to work out the values of parallel impedances.

You will become confident using phasors to represent AC values, and learn how to multiply, divide, add and subtract phasors.

You will learn how to represent impedances using complex numbers, and how to manipulate these values.
