Hello all and thanks for reading my latest posting.
I want to find the turns ratio of a coil which has primary and secondary windings.
Can someone please describe to me how I can do this using Oscilloscope, function generator, and I have 2 multimeters available.
I know I can do this by comparing the AC voltage in the primary to the AC voltage in the secondary but do I need to think about the res freq for doing this?
What voltage should I use? I was thinking of 1 volt peak AC on the primary as I know this is a step up coil to make it easier.
What freq should I use?
I notice that the 1 volt AC on the oscilloscope isnt even close to 1 volt AC I measure on my multimeters, so which one should I use to set my voltage, the funct. gen. or the multimeter?
I do not have a schematic for this as this is just a question I have and didnt think one would benefit the question any.
Thanks again for all your help.
