Has the greater electrical resistance wet skin or dry skin?
Iviesmith
If the skin is dry it will offer more resistance. The resistance of the human body ranges from about 100 ohms if the body is soaked with salt water to about 5000,000 ohms if the skin is very dry. If we touch the two electrodes of a battery with dry fingers, completing the circuit from one hand to the other, we can expect to offer a resistance of a bout 100,000 ohms. We usually cannot feel 12 volts if we do this, though a 24 volts just barely tingles. If our skin is moist, however, 24 volts can be quite uncomfortable.

What is the electrical resistance for a dry body?
low
What is human body resistance to electricity if skin is wet?
human body resistance to electricity when skin is wet is 1,000 ohm and when skin is dry its resistance is 100ohm
What is r lower for wet skin than for dry skin?
resistance for electricicty
What affects a skin's resistance?
Thin or wet skin is much less resistant than thick or dry skin
Will more current flow when the skin is wet or dry?
Any electrical current will flow better on something wet as opposed to something dry. This means that the water on wet skin will conduct the electricity better than it would be conducted on dry skin
Do dry leather gloves have electrical resistance?
Yes, dry leather has an electrical resistance of around 100kOhm, enough to protect from residential voltage, but much less than what you would want for distribution voltage. However, the resistance of leather falls dramatically (up to 95%) when damp, so rubber gloves are always required when working around high voltage.
What is resistance to the motion of an object?
Resistance to the motion of an object is friction. Several different kinds of friction exist, including dry, fluid, lubricated, skin, and internal.
What conditions make a patient micro shock sensitive?
A patient becomes micro shock sensitive if the skin resistance is bypassed such as by an intravenous infusion, or a catheter. Most of the body's resistance is in its dry skin. If the skin gets wet, salts go into ion form, thus, lowering the resistance.Ê
What is the resistance of human skin?
Measurements and research from various sources tell us that -1mA is the sensibility threshold. -5mA to 10mA hurts. -40mA causes heart disturbance. -60mA to 100mA is lethal. These are reactions of a healthy human body. Much lower currents could be lethal for persons with heart malfunctions, pacemakers or other implanted electronic devices. See related links for my source. The resistance of human skin is highly variable depending on several different variables, but the two main variables are whether the skin is clean or dirty. Clean skin often has a resistance of about 500 ohms. Dirty skin can have electrical resistances of up to several million ohms.
Does a salamander have dry skin?
No, they have wet slimy skin. Reptiles have dry skin.
Can you die from dry skin?
You will not die from dry skin, however it is possible to die from an underlined condition causing the dry skin.
How does a moisture meter give a reading of the moisture content of wood?
By passing an electrical current from one pin to the other. The greater the moisture content, the higher the resistance. By measuring the resistance, it gives an estimate of the average moisture content. I think. 2009/03/14 - Correct, but exactly backwards .... Moisture (water) can be a conductor. Dry wood is an insulator. The higher the moisture content, the lower the resistance and vice-versa. Wood with a high moisture content gives a low resistance to the tester and conducts the test voltage better.
