Current in the body. The resistance of the body varies from approximately 500 $\mathrm{k} \Omega$ (when it is very dry) to about 1 $\mathrm{k} \Omega$ (when it is wet). The maximum safe current is about 5.0 $\mathrm{mA} .$ At 10 $\mathrm{mA}$ or above, muscle contractions can occur that may be fatal. What is the largest potential difference that a person can safely touch if his body is wet? Is this result within the range of common household voltages?

Yes, it is in the range of common household voltage.

A capacitor is a passive two-terminal electrical component that stores electrical energy in an electric field. The effect of a capacitor is known as capacitance. The electrical charge stored in a capacitor is proportional to the potential difference between its terminals. A capacitor is defined as an electrical component that can store an electric charge. The effect of a capacitor is known as capacitance. The charge on a capacitor is directly proportional to the potential difference across its terminals. The unit of capacitance in the International System of Units (SI) is the farad (F), defined as one coulomb per volt. In electrical engineering, a common symbol for capacitance is the lowercase Greek letter "rho" (?). The capacitance of a capacitor is also expressed in farads.

In physics, electric flux is a measure of the quantity of electric charge passing through a surface. It is used in the study of electromagnetic radiation. The SI unit of electric flux is the weber (symbol: Wb). The electric flux through a surface is calculated by dividing the electric charge passing through the surface by the area of the surface, and multiplying by the permittivity of free space (the permittivity of vacuum is used in the case of a vacuum). The electric flux through a closed surface is zero, by Gauss's law.

recent sub human body is one kilo home when it is wet and 500 kilo home when it is very dry. The maximum safe current is award five million beer. Now here we want to calculate largest separation difference that a person can several touch if his body is right. So here we have seven grand. He called you five million beer, which is equal to five times 10 to the power. Monetary and beer re sense off the body is equal to one. You know, Um, which is equal to 1000 home when the body is what nobody using Angela Begin is nickel plated. The largest potentially friends. There's a person begins every touch. So by using the law we have the is equal to i times are here I the safe current having the value five times 10 to the power minus tree M Pierre and his sense of the body. When it is a bit, it will do those in the home. So we have potentially friends equal to five. I won't That is the maximum mortgage. Ah person begins effort if it's so if his body is. But this value exists within the range off common household word dish
