Finding ohms
WebTake these two resistors in parallel, and think about what the equivalent resistance would be. And we have seen that before. One over the equivalent resistance is going to be equal to one over 6.0 ohms plus one over 12.0 ohms. 1/6 is the same thing as two over 12. So 2/12 plus 1/12 is 3/12. And 3/12, you could view that as the same thing as one ... WebFeb 6, 2024 · In fact, if you were to use a test meter to measure the Ohms (impedance) of the voice coil on a speaker, you’d find a reading of about 3.2-3.6 ohms or so for a 4 ohm speaker and 6 ohms or higher for an 8 ohm speaker. Example of calculating speaker impedance. Let’s take an example. We’ll use an example speaker and real-world …
