   My oscilloscope reads 3 volts on DC setting and 12 volts on + peak setting.. which one do I go by when driving a FET/Transistor?

   so 12v peak volts is going to fully turn on a FET with a 3v DC reading? Ive lost one great FET ...s . I SHLD prolly post in forum issubut when I am here my typing goes all over the place and its very frustrating thinking its just this siterew is sometrhginjg definitely wromg here.
   e and also the log in boxes are very tiny. I think th

   testing testing testing testing testing.... seems to be working fine now.... 
   I need to understand the difference between a positive peak reading and a DC  reading... I cant find any documents explaining the do's and donts with peak and DC voltage readings regaurding FET's.
