No-Nonsense General Class License Study Guide: for tests given given between July 2023 and June 2027 - Tapa blanda

Sinopsis

The No-Nonsense series of amateur radio license study guides is famous for helping people pass the tests. Written in a simple, easy-to-understand style, this study guide will help you upgrade to General Class in no time. This study guide covers:

• Electrical Principles
• Circuit Components
• Practical Circuits
• Signals and Emissions
• Antennas and Feedlines
• Radio Wave Propagation
• Amateur Radio Practices
• Operating Procedures
• Electrical and RF Safety
• Commission's Rules

Every single question that you'll find on the test is included in the book. It gives you a short, "no nonsense" explanation of the topic and follows it with the question from the question pool, with the correct answer highlighted. Here's an example:

The reactance caused by a capacitor depends on the frequency of the AC source. You calculate the reactance caused by a capacitor with the equation XC = 1/(2πfC), where XC is the capacitive reactance in ohms (Ω), f is the frequency of the AC applied to the capacitor in Hertz (Hz), and C is the capacitance in farads. As you can see from the equation, as the frequency of the AC increases, the capacitive reactance decreases.

G5A06

How does a capacitor react to AC?
A. As the frequency of the applied AC increases, the reactance decreases
B. As the frequency of the applied AC increases, the reactance increases
C. As the amplitude of the applied AC increases, the reactance increases
D. As the amplitude of the applied AC increases, the reactance decreases

With this study guide, you really can upgrade to General Class, so why wait?
