What's the difference between AC and DC currents?
Is one type of current considered safer than the other?
DC current can be more dangerous because it can cause sustained muscular contraction, making it more difficult for a person to let go of a live wire. AC current can cause the muscles to spasm, which can make it easier for a person to let go. However, in high voltage situations, both AC and DC currents can be lethal.
