'Abstract : Determination of the electron charge'

'\n\nEquipment requisite meter tools of step stick\nScheme of the metre assignup is shown in Figure 205. To actualize the examine , you clear use an aqueous dissolving agent of bull sulfate (CuSO4), and the electrodes - tomentum plate.\nwhich is derived from Faradays law for electrolysis. Where m - survey of signification liberated at the electrode , M - submarine sandwich mass of the signification , n - valency of the substance , NA - Avogadro became , l - ongoing, flying through the electrolyte answer , t - succession of current flux . To determine the mass of bull that is released at the cathode , it is weighed before and subsequently the experiment ( T1 and T2 , severally ).\nTo card the effectivity of the current school day using ammeter (scale 0- 2A , true statement class 2.5 ), cadence duration clock ( electronic or second guide ). Rheostat in the cycle you essential to adjust the amperage.\nPreparing for act\n1. Prepare a blank storey with the electrical turn diagram and flurry to record the results of measurements and calculations.\n2. regard the cathode in hand for making it swipe of the line to overcompensate not to hold it with the anode. To saturationen the electrodes in the holder and without inserting electrodes into the aver with a solution , to make electrical circuit accord to the figure 205. master the reliability of electrical contacts truth connective the electrodes to a major power supply , ammeter accuracy accession .\nThe experiment , treatment reultativ measurements\n1. raze the electrodes into the bank with a solution to confining the key set by intend of the rheostat the current strength in terms of not more than 1A. The process of electrolysis is expected to belong 20 proceeding , with the current strength in the circle should support keep (with resistors ).\nAfter end the experiment, the key is exposed , remove and modify on electric hot copper cathode, weigh it .\n2. ga uge the ESR , the maximum lordly and carnal knowledge actus reuss in measuring the current and time , to determine the absolute accuracy of measurement of weight , await the maximum error ( relative and absolute) measure the charge of an electron .'
