Final answer:
Burn injuries caused by alternating current (AC) electricity tend to cause more severe damage compared to direct current (DC) because AC can lead to involuntary muscle contractions, making it difficult for a person to release from the electrical source.
Step-by-step explanation:
Alternating current (AC) results in the periodic reversal of electric charge direction. Unlike direct current (DC), which flows in one direction, AC changes direction at regular intervals.
This is seen in standard household electricity, where the current smoothly increases to a maximum, decreases to zero, and then repeats the process in the opposite direction.
The effects of AC on the body can cause deeper tissue damage due to the continuous back-and-forth flow of electricity, potentially leading to more severe burns and internal injuries. Additionally, the frequency of AC can affect the severity of the injury.
