Why AC current is dangerous than DC?

AC current is said to be more dangerous than DC current because the root mean squared value of AC is much more than its original value. Our heart is driven by electric pulses; the high electric frequency of AC current can affect the frequency of the heart and can lead to a heart attack.

What does AC current do to your body?

AC with the same amperage and voltage as DC is more dangerous and provoke worse effects on the human body. Low frequency AC provokes muscle contraction (tetany) which can induce the “cannot let go” effect by freezing the muscles of the hand.

Why are AC currents better than DC?

Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances. Although for very long distances (more than 1000 km), direct current can often be better.

Which is harmful AC or DC?

Alternating current (A.C) is five times more dangerous than Direct current (D.C). The frequency of the alternating current is the main reason for this severe effect on the human body. The frequency of 60 cycles is in an extremely harmful range. At this frequency, even a small voltage of 25 volts can kill a person.

Is AC current more dangerous than DC current?

Now, it can be summarised that AC Current is more dangerous than DC Current. Well, one should not be afraid of electricity, but one must remember that both AC current and DC current can be dangerous to the human body and safety measures must be taken into the consideration when working with any of them.

What happens when a person is electrocuted by DC voltage?

In case of DC voltage and currents, It causes a single convulsive contraction (a jerky and uncontrollable process in which muscles become shorter and tighter) which pushes the victim away from the DC current or voltage source they touched.

What is the effect of alternating current on human body?

The frequency of the alternating current is the main reason for this severe effect on the human body. The frequency of 60 cycles is in an extremely harmful range. At this frequency, even a small voltage of 25 volts can kill a person. A.C causes a severe contraction of the muscles and causes sweating.

Is 230V AC more dangerous than 230V DC?

In other words, 230V AC (or 120V AC) is more dangerous than 230V DC or 120V DC respectively. But keep in mind that DC has the ability to roast you i.e. if we say AC is more dangerous, it doesn’t mean that DC will only play with you. Stay away and don’t trust both.
