Which is more harmful, AC or DC?
One of the reasons why AC may be deemed more harmful is that it has more possibilities of entering your body. Because the voltage alternates, current can enter & exit your body even without a closed loop, as your body (and the ground it is connected to) has capacitance. That is something DC cannot do.
Which is more dangerous: current or voltage?
Higher voltage enables the generation of higher, more harmful currents. Resistance opposes current, hence high resistance is an effective shock protection strategy. Any voltage greater than 30 is generally thought to be capable of producing harmful shock currents.
What is the National Electric Code?
