Question

The electrical resistance of a healthy man is-
A) 50,000 ohm
B) 10,000 ohm
C) 1,000 ohm
D) 10 ohm

Answer 1

Answer:

Under dry conditions, the resistance offered by the human body may be as high as 100,000 Ohms. Wet or broken skin may drop the body's resistance to 1,000 Ohms,high-voltage electrical energy quickly breaks down human skin, reducing the human body's resistance to 500 Ohms.

Answer 2

The electrical resistance of a healthy man is 1000 ohm. (Option C)

• The electrical resistance of the human body is totally dependent on the external condition of the body because most of the electrical resistance is caused by the external human skin.

• Now,if the human skin is dry (dry skin condition is taken as the ideal condition because our skin stays dry for most of the time) the electrical resistance of the human body is approximately 1000 ohms.

• But,this value of the electrical resistance increases if the skin of the human body becomes far more than 1000 ohms.
