I was reading and it talks about how voltage ac is stepped up or down via an isolated transformer, correct me if i'm wrong this was a few weeks back so if 1vac went in 5ac went out, you'd have to put 1 coil on the primary and on the secondary windings, 5 coils 1*5=v
10 coils on primary, 10 coils on secondary, 1v in, 1v out.... so if the same number of coils is used, it merely passes on the magnetic field...
Let's suppose 1 coil on primary, 2 coils on secondary, 5v in, does this mean 10v comes out? and if so...
5vac
100 coils on primary, 100 coils on secondary = 5vac
100 coils on primary, 200 coils on secondary = 10vac
1 coil on primary, 1 coil on secondary = 5vac
now if that's right?, to double the voltage why spend money on wrapping
it 100 times when you could do 1 coil on primary and 2 coils on secondary
doubling your voltage??... Which leads me to the ultimate question, how do you know how many volts / amps come out of the other end...
So could I use a Transformer as some kind of Resistor or Regulator?, for example you wish to work with 12v but you don't ever want to exceed
10ma at 12v
instead of 1000 windings, simply have say 20 windings on the Primary and 20 on the Secondary, that should give the same voltage out (12v) however the current should be low right?...
Could that be used to power LED's and keep them regulated, you could then use a 12v source directly onto the LED it'll always be low current keeping the LED regulated until the voltage drops below 3volts or so.
