Final answer:
Electrical burns are more serious than they appear on the body surface and extremities, particularly the digits. The electrical current can disrupt the heart's electrical patterns and cause burns.
Step-by-step explanation:
Electrical burns are indeed more serious than they appear on the body surface and extremities, particularly the digits. While the skin may only show minor damage, the internal tissues and organs can be severely affected.
When a person receives an electrical shock, the electrical current can disrupt the heart's electrical patterns, leading to irregular and ineffective beating, which can be fatal. Additionally, the shock can cause burns depending on the concentration of current, with higher concentrations increasing the likelihood of burns.
