? Which is more dangerous DC or AC current


Peace be upon you, followers and visitors to the blog of invention plus, in this topic we will answer the most frequently asked question, which is the most dangerous DC or AC with a detailed explanation, as well as explaining some terms such as what is AC and what is DC, definition of frequency and how it is measured Read on to find out the answer


:  About AC


Alternating electric current, also called alternating current and denoted by the symbol AC, is a current that does not have polarity, i.e. negative and positive, but in it there is a phase wire, which represents the positive, and the neutral wire, which represents the negative, and there are two basic  systems


 :Single-phase system


 It consists of the neutral wire and the phase so that the phase wire is the one that carries the current, and the voltage difference between them is often 220 volts. Different frequency according to countries. It is used in residential homes Three-phase system: It consists of three wires representing the phase wire, and the voltage difference between them is 380 volts, and it is considered three times more dangerous than the other system, and it is used frequently in factories, industrial facilities, and some residential and commercial buildings. It is also used in electricity distribution.


:What is the frequency


 It is the unit for measuring the electrical frequency at which both voltage and electric current fluctuate, and it is symbolized by the letter (Hz). This applies to alternating current (AC) only, and it is in the electricity distribution network between 50 and 60 Hz.


:The answer to the question


 In general, AC alternating current is more dangerous to humans than DC current, this is for low frequencies and the effect of alternating current 50 and 60 Hz is more dangerous between 3 and 5 times that of direct current at the same voltage value.


Important notes: The danger of alternating current varies according to the frequency value, which is according to a special curve, and the highest value for the danger reaches at the frequency of 50-60 hertz.


Alternating current with high frequencies and high current is considered less dangerous compared to the same value for DC current.


One of the most dangerous things that the injured person is exposed to in the electric shock is the phenomenon of fibrillation, which is the phenomenon of tachycardia, and therefore the blood pumping stops or the pumping is weak, and the cause of this phenomenon is the alternating current. A right hand is more dangerous than a left hand - a left man

The risk depends, in addition to the value of the current and the type of current, on the time to which it is exposed, and the time curve is not linear and varies between DC and alternating current.
