why blood burn when human touch electric wire
Answers
Answer:
Explanation:
The burns or the thermal damages in an electric shock are due to joules heating(i^2rt).
The scale of damage depends on 7 factors: (1) type of current, (2) amount of current, (3) pathway of current, (4) duration of contact, (5) area of contact, (6) resistance of the body, and (7) voltage.
Human body can be considered as a leather bag filled with electrolytic fluid. The outermost skin has the highest resistance and and as one goes deeper resistance decreases. This is due to our well developed nervous system.
This allows electricity to flow through our body causing heating which results in burns.
The flow of electrons inside the wire causes burn and also damages our nervous system. It causes heat in our body which burns our blood and we finally die.
