## What is the minimum resistance of human body?

According to National Institute of occupational safety and health, Under dry condition, the resistance of the human body is 100,000 ohms. Under wet condition, the resistance is reduced to 1000 ohms. When electrical energy of high voltage gets into the human skin, the resistance is reduced to 500 ohms.

## What is the normal resistance of a healthy human body?

Human resistance is about 10,000 ohms on the high side and as little as 1,000 ohms if the person is wet. Remember, ohms is the unit of measure of a material’s resistance or impedance to current flow.

What is a low resistance?

What is a Low Resistance Measurement? A low resistance measurement is typically a measurement below 1.000 ohm. At this level it is important to use test equipment that will minimize errors introduced by the test lead resistance and/or contact resistance between the probe and the material being tested.

### Why is low resistance dangerous?

Wet working conditions or broken skin will drastically reduce resistance. The low resistance of wet skin allows current to pass into the body more easily and give a greater shock.

### What causes low resistance?

All conductors give off some degree of heat, so overheating is an issue often associated with resistance. The lower the resistance, the higher the current flow. Possible causes: insulators damaged by moisture or overheating.

Is low resistance Good or bad?

The amount of resistance a resistor has is determined by the relationship of the current through it to the voltage across it which determines whether the circuit element is a “good conductor” – low resistance, or a “bad conductor” – high resistance. Remember that resistance is always positive, and never negative.

#### What happens if the skin resistance is low?

If skin resistance is low, few, if any, burns occur, although cardiac arrest may occur if the current reaches the heart. If skin resistance is high, much energy may be dissipated at the surface as current passes through the skin, and large surface burns can result at the entry and exit points.

#### CAN 5000 Volts kill you?

What damage could a 5000 volt shock do to the body? In fact, besides a little neurotic “shock”, the voltage itself makes no damage if the current doesn’t exceed 15 mA (0.015 A). However, if you touched the 7 KV source with one hand, and ground with your other, you could be killed.

Do you take the path of least resistance?

This thinking still exists. Some equipment installation instructions require a ground rod without an equipment grounding conductor, claiming it’s a safe installation. Electricity does take low-resistance paths, including the one of least resistance. But it also takes every other path available to it.

## What is the safe current of the human body?

Human body safety voltage Industry regulations The safety voltage is not higher than 36V, the continuous contact safety voltage is 24V, and the safe current is 10mA. The degree of damage to the human body caused by electric shock depends mainly on the magnitude of the current through the human body and the length of the power-on time.

## Which is more dangerous high voltage or low resistance?

Higher voltage allows for the production of higher, more dangerous currents. Resistance opposes current, making high resistance a good protective measure against shock. Any voltage above 30 is generally considered to be capable of delivering dangerous shock currents. Metal jewelry is definitely bad to wear when working around electric circuits.

Which is part of the body has the least resistance?

Within the body, the tissues with the greatest resistance are bone and fat – nerves and muscle have the least resistance. That said, the majority of the body’s resistance is in the skin – the dead, dry cells of the epidermis (the skin’s outer layer) are very poor conductors.

### Why do some people have lower electrical resistance than others?

There are a lot of factors involved and not every person has the same electrical resistance. For instance, men tend to have lower resistance than women. Just like for the resistors used in electronics, the resistance of a person’s arm depends on the arm’s length and diameter.

### Why do men have lower resistance than women?

For instance, men tend to have lower resistance than women. Just like for the resistors used in electronics, the resistance of a person’s arm depends on the arm’s length and diameter. Resistance goes up with length and down with diameter. Since men tend to have thicker arms and legs (more muscle), they usually have lower resistance.
