It's way cheaper. Like, it's not even close.
(Note that this IS galvanic isolation--I assume you are talking about transformers, which is the other common way to galvanically isolating circuits.)
- jeffbee 4y agoYou’re right that was lazy of me. But you got what I meant: transformers.
- fuzzfactor 4y agoMagnetic isolation more specifically, when you think about it. So at the same time, magnetically coupled. Naturally subject to forces including back-EMF which are not shared by optics.
- klodolph 4y agojust drive your optics hard enough, you'll see back-EMF /s
- fuzzfactor 4y agoI've driven non-photo resistors to the point you could see the glowing in time to the music ;-) And smell the smoke. Now with a 1500W space heater as a dummy load on a 1000W amp, you hear a little music come out of the heating elements without any speakers.
