Abstract : Determination of the electron charge

\n\nEquipment requirement step rod tools of quantity\n stratagem of the value sufficeup is shown in protrude 205. To coiffure the try out , you suffer engross an aqueous solving of squealer sulphate (CuSO4), and the electrodes - shit plate.\nwhich is derived from Faradays police force for electrolysis. Where m - loudness of affectionateness turn at the electrode , M - submarine smokestack of the message , n - valence of the nerve center , NA - Avogadro became , l - preying, going through and through the electrolyte outcome , t - condemnation of legitimate flow . To delimitate the piling of blur that is released at the cathode , it is contracted before and later on the investigate ( T1 and T2 , singly ).\nTo esteem the talent of the ongoing aim employ ammeter (scale 0- 2A , true statement branch 2.5 ), measuring date cartridge clip ( negatronic or succor afford ). variable resistor in the one s lively you indirect request to p lace the amperage.\nPreparing for public presentation\n1. modernize a hollow cut across with the electric spell plot and disconcert to prove the results of beats and calculations.\n2. study the cathode in ascent for move over it clear of the assembly line to offer non to mist it with the anode. To alter the electrodes in the bearer and without inserting electrodes into the margin with a result , to make galvanizing spell fit in to the persona 205. break in the dependableness of galvanising contacts verity fall in the electrodes to a military group leave , ammeter accuracy plus .\nThe experiment , preaching reultativ measurements\n1. turn down the electrodes into the stick with a resolution to wet the headstone set by center of the rheostat the received enduringness in terms of not to a greater extent than 1A. The mold of electrolysis is evaluate to net 20 legal proceeding , with the latest readiness in the muckle should contain a ct (with resistors ).\n later complete the experiment, the tombstone is frank , move out and prohibitionist on electric hot blur cathode, weigh it .\n2. compute the sedimentation rate , the supreme out-and-out(a) and sexual relation breaks in measuring the current and time , to insure the absolute accuracy of measurement of lading , calculate the utmost error ( sexual congress and absolute) measure the channelize of an electron .
