AVIXA Recognized AV Technologist Test

The term that is used to quantify both resistance and impedance is ohms. Resistance is a measure of how much a material opposes the flow of electric current, and this opposition is quantified in ohms (Ω). Similarly, impedance extends this concept to AC (alternating current) circuits, incorporating not only resistance but also reactance, which accounts for the effects of capacitance and inductance. Therefore, impedance is also measured in ohms, making it the appropriate unit for both types of electrical opposition. This understanding is critical for AV technologists, as it relates directly to the design and troubleshooting of audio and video equipment within electric circuits. Recognizing that ohms serve as the unified measurement for both resistance and impedance allows for a deeper comprehension of circuit dynamics and signal transmission in AV systems.
