Does the US use AC or DC?
Today our electricity is still predominantly powered by alternating current, but computers, LEDs, solar cells and electric vehicles all run on DC power. And methods are now available for converting direct current to higher and lower voltages.
Which is safer AC or DC?
An electric shock has the capacity to induce ventricular fibrillation which can lead to heart failure and death. Avoiding any form of electric shock is preferable, but DC is considered safer in these circumstances as the human body’s threshold to DC is considerably higher than to AC.
Can DC power kill you?
Either AC or DC currents can cause fibrillation of the heart at high enough levels. 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.
