The correct answer is: D. None of these
The resistance of the human body is not a constant value, but varies depending on a number of factors, including the person’s age, health, and skin condition. In general, the resistance of the human body is in the range of
100,000 to 100,000,000 ohms. However, this can vary greatly from person to person. For example, the resistance of a person’s skin can be affected by the amount of sweat on their skin. Sweat is a good conductor of electricity, so it can lower the resistance of the skin.The resistance of the human body is also affected by the amount of moisture in the air. When the air is dry, the resistance of the human body is higher. This is because the dry air does not conduct electricity as well as moist air.
The resistance of the human body is also affected by the voltage of the current. The higher the voltage, the lower the resistance of the human body. This is because the higher voltage can overcome the resistance of the skin and other tissues.
In general, the resistance of the human body is high enough to prevent a person from receiving a shock from a low-voltage source, such as a battery. However, if the voltage is high enough, the resistance of the human body can be overcome and a person can receive a shock.
The severity of a shock depends on a number of factors, including the voltage of the current, the length of time the current is flowing, and the path of the current through the body. A shock can cause a number of symptoms, including pain, muscle contractions, and cardiac arrest. In severe cases, a shock can be fatal.
