Web4 mrt. 2006 · What I know is that 50Hz current is more dangerous than DC current.However when the frequency increases the effect of the current decreases below that of DC current.You can test it easily with 60V AC and DC.That is,if you are not "superconductive". I personally almost do not feel 60V DC but 60V AC tickles a little. Web26 apr. 2024 · Therefore, AC current is more dangerous than DC current because it has a greater magnitude than its RMS value; ... This typically takes place at 30 mA of AC (rms, 60 Hz) or 300 – 500 mA of DC. Though both AC and DC currents and shock are lethal, more DC current is required to have the same effect as AC current.
Web17 mei 2024 · AC Power is four to five times dangerous than DC having same level of voltage. There's a couple of reason for this. The first is that when someone mentions an AC voltage that means mentioning the effective value or RMS value. So the peak value of AC is higher RMS value as Peak value = √2 xRMS value. As we know for AC - V = Vₚ sinωt Web8 okt. 2024 · Now, we will discuss AC or DC electricity which is more dangerous frequency to the human body As indicated in fig 2, the male body has better resistant to electrical …
WebAC is not always less dangerous. The power grid frequency of 50 or 60 Hz is quite dangerous. However, if an AC power source is high in frequency, say 100 kHz or higher, …
WebDirect current (DC) is more likely to cause muscle tetanus than alternating current (AC), making DC more likely to “freeze” a victim in a shock scenario. However, AC is more likely to cause a victim’s heart to fibrillate, which is a more dangerous condition for the victim after the shocking current has been halted. Comments
WebAnswer (1 of 4): This is open to debate. There are many differing opinions.
