Answer

These behave like ordinary thermal burns and range from local erythema to full-thickness burns. These require several seconds of contact to cause skin burns, sometimes reaching current levels high enough to cause VF before causing any significant skin damage. [4] Direct contact burns may occur only if the circuit through the person was prolonged for more than a few seconds. Low-voltage burns are shown below.
