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

Hint: An electrical shock is the human body's involuntary response when electrical current is passed through the body. An electrical shock happens when a person comes into contact with an electrical source.

Complete step by step solution:
The electrical shock is the cumulative result of the potential difference, the electrical current and the resistance of the human body.When electricity travels through anything alive, electrocution or electric shock occurs. It develops when the human body comes into contact with electricity. Electrical energy flows into a part of the body that produces a shock. Exposure to electricity can result in no harm at all or can lead to devastating damage or death. The most common electrical shock injury is burns.

An electrical shock may be encountered where there is a potential difference in one part of the body and the other. As the current flows into the human body, it prefers a direction that provides low resistance. The body's resistance is not consistent in the body. As long as the current flow continues within the body, the current and resistance of the human body begins to shift inversely.

Additional information:
Electrocution is death or permanent injury due to electrical shock, electrical current flowing through the body. The term is derived from "electro" and "execution," but is often used for sudden death. The word "electrocution" was coined in the US in 1889 shortly before the first use of the electric chair and initially applied only to electrical execution and not to accidental or suicide electrical deaths.

Note: For understanding the concept of electric shock we have to understand the properties of electric current, resistance and potential difference of the human body.
