I created a boost converter as given here:Boost converter transistor voltage weird behavior I do not know what happened but as i connected a smaller capacitor about 22pF at the output in parallel with the 1kOhm resistor the oscilloscope showed an inductive kickback of 100 volts every switching period (I even saw a spark). The boost converter is powered by a 1Volt battery. My question is are these sparks dangerous if I were to accidentally touch them and why did the smaller capacitor contribute to inductive kickback?
