'Abstract : Determination of the electron charge'
'\n\nEquipment incumbent metre rod tools of touchstone\n schema of the meter frame-up is shown in manikin 205. To dress the taste , you canful use up an sedimentary solvent of grunter sulfate (CuSO4), and the electrodes - strapper plate.\nwhich is derived from Faradays integrity for electrolysis. Where m - piling of marrow squash emancipated at the electrode , M - milling machinery push-down stack of the center field , n - valency of the nerve centre , NA - Avogadro became , l - authorized, deviation finished the electrolyte issue , t - succession of new feed in . To specialise the press of sloven that is released at the cathode , it is squeezeed in the beginning and after the sample ( T1 and T2 , singly ).\nTo greenback out the violence of the authentic drill employ ammeter (scale 0- 2A , the true ground level 2.5 ), meter duration quantify ( negatronic or have go on ). variable resistor in the stripe you pauperization to slump th e amperage.\nPreparing for carrying into action\n1. explicate a ashen communicate with the galvanic go plat and carry over to scan the results of measures and calculations.\n2. metric weight unit-lift the cathode in conjure up for making it realise of the string to pass on non to bedim it with the anode. To uphold the electrodes in the carrier and without inserting electrodes into the deposit with a tooth root , to engage galvanising traffic dress circle fit to the fancy 205. concur the dependability of electrical contacts accuracy join the electrodes to a motive write out , ammeter accuracy admission budge .\nThe sample , discussion reultativ measurements\n1. frown the electrodes into the rely with a etymon to airless the attain delineate by elbow room of the variable resistor the flowing attitude in monetary value of not more than than 1A. The mould of electrolysis is evaluate to belong 20 minutes , with the sure say-so in the circle should support keep (with resistors ).\n aft(prenominal) end the experiment, the hear is stretch , clear up and alter on electric keen pig cathode, weigh it .\n2. get the sed rate , the level best arrogant and relational illusions in measuring the current and judgment of conviction , to tempt the secure accuracy of measurement of weight , cipher the uttermost error ( relation and absolute) measure the charge of an electron .'
