Hi there guys and gals!!
This is my first time posting on this forum so don't bash me to hard.
I recently bought an oscilloscope and want to make an octopus curve tracer. There are many schematics online that I have seen. Most of them are using a 120v ac in to 6.3v ac out. Then they're only using one secondary wire and the center tap to get 3.15v ac. also the device under test(DUT) is seeing a max 1v 1ma? am i understanding this correctly?
Basically what i want to do is use a transformer that i already have. Problem is its output is 9v 800ma? I don't know if it has a center tap or not as i haven't tore the wall wart apart yet. i have learned OHM's law and am getting familiar with Kirchoffs law thinking i can figure out the different resister values to get me down to 1v 1ma for the DUT. Am i on the right track . please help me with this so i can learn in the process
