# Craft Skills - Basic Electrical Concepts

## Course Number - EMS100

### Course Purpose

This course provides information on the basic concepts of direct current (DC) electricity and magnetism, including electrostatics, basic circuit concepts, and measurement of electrical quantities and associated numerical concepts, Ohm's Law, practical circuits, electromagnetism, and electrical measurements. There are hands-on exercises for device operation and simple circuit construction and analysis.

You will then be presented with a systematic strategy for diagnosing and troubleshooting a variety of common system errors:

• Identify the types of electrical energy.
• Discuss the composition of the atom and its relation to an electrical charge.
• Explain the characteristics of current, voltage, and resistance.
• Explain Kirchhoff's Current Law and Kirchhoff's Voltage Law.
• Calculate the equivalent resistance of series and parallel resistive circuits.
• Calculate DC circuit parameters using Ohm's Law, Kirchhoff's Current Law, and Kirchhoff's Voltage Law.
• Describe the characteristics of capacitors and capacitance.
• Describe the characteristics of inductors and inductance.
• Describe the construction and operation of a simple AC generator.
• Define inductive reactance.
• Calculate the inductive reactance of a simple AC circuit.
• Define capacitive reactance.
• Calculate the capacitive reactance of a simple AC circuit.
• Define impedance.
