A battery, which is actually an electric cell, is a device that produces electricity from a chemical reaction.Strictly speaking, a battery consists of two or more cells connected in series or parallel, but the term is generally used for a single cell.A cell consists of a negative electrode; an electrolyte, which conducts ions; a separator, also an ion conductor; and a positive electrode.hen the cell is connected to an external load, or device to be powered, the negative electrode supplies a current of electrons that flow through the load and are accepted by the positive electrode. When the external load is removed the reaction ceases.
It's between 115.51 and 116.55, depending upon whether one uses an SD of 15 or 16. Now, this isn't absolute and conclusive proof that Obama's IQ is 116, as it could well be a little bit higher or a little bit lower. But not much higher, because if he scored even 100 points more on the SAT, he wouldn't have had to go to Occidental in the first place.
Research comparing IQ to presidential performance points to yes. Compared to the general population, presidents are smart people. The average IQ score in the general population is 100; about 118 for for a college graduate. All the U.S. presidents have higher IQs than that. But some are geniuses. Anything over 130 is considered high or a genius-level IQ. From Washington to George W. Bush, 28 U.S. presidents met that mark. Only 3 percent of Americans score above 130. Bill Clinton had the fifth-highest IQ. Note that Obama is not included in these data points.
