You can use transformers to add or subtract AC
(lemmings.world)
I'm just following the rules of the community and this has. Been on my mind for the past few days . I used to be able to listen into law enforcement and even automated the process but they upgraded their system and encrypted their system.
Now I'm theorizing how I can track law enforcement different ways one of which is using a direction finding system. i could super technical and order a bunch of parts and have a desktop running all the time or I can try to dumb it down with analog composition.
I think it's cool that you can add AC with a ring of iron and winding wires in a specific way (the other way will subtract it)
You don't "add AC", the power in the circuit is exactly the same, if you double the voltage you halve the current, its not magic!!!!
Yes, but if you induce current in two coils, you get their sum as the output
I should say constructive interfer inside the core of the transformer. I would only care about voltage because I want to hook up my antenna to an adr to scan multiple frequencies.
