High voltage vs high current
WebJun 11, 2024 · AC is more dangerous than DC because the peak voltage is higher (which causes higher peak current that breaks down skin resistance more) and it reverses polarity regularly giving the effect of multiple shocks. The heart is particularly sensitive to mains frequency AC because it will try to follow the frequency and go into fibrillation. WebOct 31, 2024 · Because the insulation resistance and reactance of the stray capacitance is so high, the ac test current can be simplified to the leakage current at 250 V times the ratio of hi-pot test voltage to 250 V. If the test voltage is 3000, then the test current would be 3000/250 x 0.5 or 6 mA.
