Why AC is more dangerous than DC? 

1 Answer

Answer :

Because the excitatory action of current (stimulation of nerves and muscle, induction of cardiac atrial or ventricular fibrillation) are linked to the changes of current magnitude especially when making and breaking of the current. To produce the same excitatory effects the magnitude of direct current flow of constant strength in 2 to 4 times greater than that of alternating current.
