WebIf you have a dc voltage of x volts, this is the maximum voltage you can get from it. If you have an ac voltage of x volts, the maximum voltage is more than x (I forgot how to calculate it, maybe it x 2, someone correct me if I'm wrong). This is because the voltage rating is the average of the oscillating voltage (after taking all positive). Web12 de fev. de 2010 · Normally, you "play it safe" with AC vs. DC and just assume they're equally dangerous. e.g. DC is less likely to cause fibrillation, but you treat it as if it were equally dangerous.
