Soft cover. Condizione: Very Good. WHEATSTONE, Charles. An Account of Several New Instruments and Processes for Determining the Constants of a Voltaic Circuit." In: Philosophical Transactions of the Royal Society. London, Vol. 133, Part II, 1843, pp. 303-327, with two folding plates (XVI-XVII). This is the entire Wheatstone paper, disbound from the l;arger bound volume. Very good condition overall, except that the plates have some foxing and are in GOOD condition. [++] "In 1843 Wheatstone published an experimental verification of Ohm's Law, helping to make the law (already well known in Germany) more familiar in England. In connection with the verification he developed new ways of measuring resistances and currents. In particular, he invented the rheostat and popularized the Wheatstone bridge"--Complete DSB online.

Frst appearance of an importent paper in the history of electricity. "In 1843 Wheatstone published an experimental verification of Ohm's law, helping to make the law (already well known in Germany) more familiar in England. In connection with the verification he developed new ways of measuring resistances and currents. In particular, he invented the rheostat and popularized the Wheatstone bridge (in the paper offered), originally invented by Samuel Christie."(DSB).
