My question is: Is it wise or good practice to use a voltage divider on the AC side of the bridge to knock down the voltage so the 7805 doesn't have to get rid of so much?
I just looked and both the 7805 and 7812 say 35v max, and when I hooked up the caps and bridge I got over 40v with no load. Is there an easy way to knock this down?
although finding one that goes above 40V may be difficult.
I found one that goes up to 40V at
Does anyone have any thoughts about induced voltage being used for something like this?
I saw somewhere a small device that I think was meant to measure load on an AC line like an amprobe ??
Again also, can someone give their opinion of a tiny transformer.
What is the difference between a signal transformer and a power transformer?
