What term is used to quantify resistance and impedance?

Ohms are used for both resistance and impedance
Capacitance is used for resistance and ohms are used for impedance
Ohms are used for resistance and reactance is used for impedance
Ohms are used for resistance and henrys are used for impedance

The correct answer is: Ohms are used for both resistance and impedance

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.
