What Actually Kills, AC Or DC?

Both alternating current and direct current are dangerous, but alternating current is considered more dangerous than direct current.

This is because the human body has a higher impedance to direct current than alternating current, so the human body can withstand the impact

Electric shocks caused by direct current are much easier to prevent than those caused by alternating current

. If current passes from one hand to the other as it passes through the heart, cardiac fibrillation may occur.
