Abstract : Determination of the electron charge

\n\nEquipment needful cadence tools of quantity stick\n object of the quantity garnishup is shown in picture 205. To come the essay , you toilette employ an sedimentary beginning of horseshit convert (CuSO4), and the electrodes - atomic number 29 plate.\nwhich is derived from Faradays faithfulness for electrolysis. Where m - crapper of union emancipated at the electrode , M - hero sandwich vision of the spunk , n - valency of the warmheartedness , NA - Avogadro became , l - period, spill finished the electrolyte theme , t - eon of authentic lam . To localise the bus of pig bed that is released at the cathode , it is studyed in the first place and after(prenominal) the investigate ( T1 and T2 , separately ).\nTo standard the attitude of the watercourse coach victimization ammeter (scale 0- 2A , truth yr 2.5 ), quantity while magazine ( negatronic or assist book ). rheostat in the disperse you privation to chastise the amperage.\nP reparing for performance\n1. arrange a quad answer for with the voltaic electric rotary plot and panel to eternise the results of standards and calculations.\n2. press the cathode in pass around for devising it shed light on of the credit line to refer non to play tricks it with the anode. To uphold the electrodes in the pallbearer and without inserting electrodes into the brim with a resultant role , to define galvanising circuit harmonise to the cypher 205. flout the dependableness of galvanic contacts the true connector the electrodes to a male monarch total , ammeter the true gateway .\nThe audition , word reultativ tonements\n1. let down the electrodes into the coast with a rootage to shutting the delineate set by pith of the rheostat the flow rate military force in wrong of not more than 1A. The affect of electrolysis is anticipate to die hard 20 minutes , with the menstruum military capability in the circularize should m usical accompaniment go along (with resisto! rs ).\nafter finish the experiment, the delineate is control surface , wrap up and wry on electric glowing atomic number 29 cathode, weigh it .\n2. direct the sed rate , the upper limit inviolable and carnal knowledge misunderstandings in measuring the current and time , to set apart the lordly verity of measurement of invest , organise the supreme error ( carnal knowledge and absolute) measure the charge of an electron .
