When To Call a Doctor. Call or other emergency services immediately if you have vertigo (a spinning sensation) and: 1  You passed out (lost consciousness). 2  You have symptoms of a stroke, such as:  Sudden numbness, tingling, weakness, or loss of movement in your face, arm, or leg, especially on only one side of your body.
High quality deionized water has a conductivity of about 5.5 Î¼S/m, typical drinking water in the range of 5-50 mS/m, while sea water about 5 S/m (i.e., sea water's conductivity is one million times higher than that of deionized water).n alternating voltage is used in order to avoid electrolysis. The resistance is measured by a conductivity meter. Typical frequencies used are in the range 1â3 kHz. The dependence on the frequency is usually small, but may become appreciable at very high frequencies, an effect known as the DebyeâFalkenhagen effect.
The more common lithium-polymer uses moist electrolyte to enhance conductivity. All batteries achieve optimum service life if used at 20Â°C (68Â°F) or slightly below. If, for example, a battery operates at 30Â°C (86Â°F) instead of a more moderate room temperature, the cycle life is reduced by 20 percent.At 40Â°C (104Â°F), the loss jumps to a whopping 40 percent, and if charged and discharged at 45Â°C (113Â°F), the cycle life is only half of what can be expected if used at 20Â°C (68Â°F).he more common lithium-polymer uses moist electrolyte to enhance conductivity.
