LESSON 1
OVERVIEW
LESSON DESCRIPTION: Upon completion of this subcourse, you will be able to
mathematically calculate how an AC circuit is designed to operate and locate problems in the
circuit. You will use simple trigonometric functions, the Pythagorean theorem, and work with
coordinates, axes, and vectors.
TERMINAL LEARNING OBJECTIVE:
ACTION:
You will solve for an unknown side of a right triangle using trigonometric
functions and Pythagorean theorem, determine the angles of right triangle
using trigonometric functions, plot a sine wave, determine the magnitude
of the x and y-vectors for a given angle, and relate coordinate notation and
vectors to sine waves.
CONDITION:
Given trigonometric tables and appropriate information about the lengths
of sides of triangles, magnitude of vectors, and angles of vectors.
STANDARD:
All calculations are performed correctly to one decimal place.
INTRODUCTION
A.C. circuits work differently than D.C. circuits. You will learn how to calculate and
monitor the operation of a circuit. In troubleshooting an electronic piece of equipment, you
need a good understanding of what is supposed to happen, and what is actually happening.
By mathematical calculations, you will figure what is supposed to happen, and by using test
equipment, you can determine what is actually happening.
