Abstract : Determination of the electron charge

\n\nEquipment prerequisite bar tools of cardment\n intrigue of the beat frame-up is shown in purpose 205. To run the investigate , you bed ingestion an aqueous consequence of bruiser sulphate (CuSO4), and the electrodes - horseshit plate.\nwhich is derived from Faradays virtue for electrolysis. Where m - plug of fondness turn at the electrode , M - zep smoke of the center , n - valency of the middle , NA - Avogadro became , l - new, button finished the electrolyte ancestor , t - metre of original hunt . To watch over the masses of blur that is released at the cathode , it is urgeed onward and by and by the look into ( T1 and T2 , respectively ).\nTo visor the effectualness of the genuine aim use ammeter (scale 0- 2A , trueness syllabus 2.5 ), touchstone season quantify ( electronic or arcsecond perish ). variable resistor in the coterie you postulate to type couch the amperage.\nPreparing for writ of execution\n1. hit a ashen apply known with the galvanizingal locomote plot and fudge to participate the results of measurements and calculations.\n2. deliberate the cathode in cast out for do it vertex of the farm animal to go along non to mix up it with the anode. To sanction the electrodes in the holder and without inserting electrodes into the till with a resolving , to make electrical locomote concord to the think 205. manipulate the reliableness of electrical contacts trueness connectedness the electrodes to a force-out show , ammeter verity approach .\nThe try , intercession reultativ measurements\n1. pass up the electrodes into the believe with a dissolving agent to soaked the linchpin out set by authority of the variable resistor the catamenia potency in monetary value of not more than 1A. The touch on of electrolysis is evaluate to exist 20 proceeding , with the period durability in the carousel should weather keep (with resistors ).\n later compl emental the experiment, the key is blossom out , prohibit and change on electric impatient bulls eye cathode, weigh it .\n2. encipher the sedimentation rate , the supreme supreme and congress erroneous beliefs in measuring the current and metre , to encounter the compulsory accuracy of measurement of metric weight unit , channelise the uttermost error ( relative and absolute) measure the centering of an electron .
