The No-Nonsense Technician Class License Study Guide is the quickest way to get your license.  It clearly and succinctly explains the concepts, while at the same time, give you the answers to all of the questions that you’ll find on the test.

Here’s an example:

Voltage is the force that causes electrons to flow in a circuit. Voltage is sometimes called electromotive force, or EMF. Voltage is the electrical term for the electromotive force (EMF) that causes electron flow. (T5A05) The volt is the basic unit of electromotive force. (T5A11) The letter V is shorthand for volts.

You use a voltmeter to measure electric potential or electromotive force. (T7D01) About 12 volts is the amount of voltage that a mobile transceiver usually requires. (T5A06)

Read through the study guide a couple of times, take some practice tests online, and you’ll be ready for the test in no time!

The No-Nonsense General Class License Study Guide is the quickest way to upgrade from Tech to General.  It clearly and succinctly explains the concepts, while at the same time, give you the answers to all of the questions that you’ll find on the test.

Here’s an example:

Reactance is opposition to the flow of alternating current caused by capacitance or inductance. (G5A02) We use the letter X to stand for reactance. Reactance causes opposition to the flow of alternating current in an inductor. (G5A03) Reactance causes opposition to the flow of alternating current in a capacitor. (G5A04)

The reactance caused by a capacitor or inductor depends on the frequency of the AC source. You calculate the reactance caused by an inductor with this equation:

X_L = 2?fL

where X_L is the inductive reactance, f is the frequency of the AC source, and L is the inductance in henries. As the frequency of the applied AC increases, the reactance of an inductor increases. (G5A05)
