reek v. Old English recan (Anglian), reocan (West Saxon) emit smoke, from Proto-Germanic *reukanan (cf. Old Frisian reka smoke, Middle Dutch roken, Dutch rieken to smoke, Old High German riohhan to smoke, steam, German rauchen to smoke, riechen to smell).
Ohm's law states that the current drawn depends on the resistance of the body. The resistance of human skin varies from person to person and fluctuates between different times of day. The NIOSH states 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, adding that high-voltage electrical energy quickly breaks down human skin, reducing the human body's resistance to 500 Ohms.
The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction. The SI unit of electrical resistance is the ohm (Ï), while electrical conductance is measured in siemens (S). An object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area.
