What do you mean by electric shock? Explain how it takes place.

Answer:

1. An electric shock is caused when there is a potential difference between two body parts.

2. When current flows through a human body, it chooses path which offers low resistance.

3. The resistance of a human body is not uniform across all body parts.

4. When current flows through low resitant parts like blood, muscles and internal organs, their resitance decreases further.

5. This causes the damage of organs and eventually causes the death.

6. Hence, electric shock is a combined effect of potential difference, current and resistance of human body.
