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.
Resistance measurement The common values of resistancefor a platinum RTD range from 10 ohms for the bird-cage model to several thousand ohms for the ï¬ lm RTD. The single most common value is 100 ohms at 0Â°C. The DIN 43760 standard temperature coefï¬ cient of platinum wire is Î± = .00385.he four-wire resistance measurement may not be required as it is with RTDâs. For example, a common thermistor value is 5000 Ï at 25Â°C. With a typical TC of 4%/Â°C, a measurement lead resistance of 10 Ï produces only .05Â°C error.
