Electrical Principles (T5)

Overview

In this lesson you will learn the vocabulary associated with electronic circuits. You will learn about electrical units and the relationships between them. This section will also teach you some simple basic circuits and present you with Ohm’s Law, which is a very helpful math equation which will explain the relationship between some of these electrical units. This lesson is the most technical and most mathematical lesson we will have in this course, try not to get too intimidated. The course starts with this lesson so that you will have the most time to let it soak in before the exam.

There are four topics covered by today’s lesson:

T5A – Current and voltage: terminology and units, conductors and insulators, alternating and direct current

T5B - Math for electronics: conversion of electrical units, decibels

T5C – Capacitance and inductance terminology and units; Radio frequency definition and units; Impedance definition and units; Calculating power

T5D – Ohm’s Law; Series and parallel circuits
