induction pulse field effect test

induction oscillation field effect tests. Unless I’m mistaken {it’s possibly happened} there is an error as there should be no field effect potential being indicated on the blue probe that is currently reading 19.3~ v that is connected on the aft side of the 100nf condenser from the input side of the inductor, the 100nf condenser should nessecaily block ‘DC’ or the straight field effect potential between the two polarity that are input in this case 20v So I don’t fully understand why when that probe is set between the equalization of that potential then it is reading ‘19.3~v’ my own tests which I will conduct again indicate a variable response at that vector but no potential that originates from alone the source , because as stated the 100nf should not allow non rotational field effect to pass as it would only have a single polarity.
