How to pronounce “ohms” in English

So you might think just add 40 ohms of resistance, but a resistor loses power through heat.

So you may have 10 ohms in a 1 k, and you'll have 100 ohms at 20 k.

So the antenna array is at 12.5 ohms, and the transmission line is at 50.

Most transmission lines today have a characteristic impedance of 50 ohms, but that value can change.

So the measurement in the lab gave us 36 ohms of real resistance and 74 ohms of reactance, so we have to match that impedance.

That leaves the real part, 10 ohms, and we need 50.

But as soon as you high pass it out to 4k, it measures 20 ohms, right?

Now, in most radio frequency or RF systems, this is designed to be 50 ohms of pure resistance.
