A Determination of the International Ampere in Absolute Measure Excerpt From A Determination Of The International Ampere In Absolute MeasureInasmuch As Precise Electrical Measurements Are Usually Made In Terms Of Standard Resistances And Standard Cells, It Would Simplify The Problem If A Voltage Instead Of A Current Were Directly Determined In Absolute Measure The Direct Determination Of The Volt With Precision In Absolute Measure, However, Presents Very Formidable Difficulties And Has Never Been Made It Was Largely For This Reason That The Ampere Was Chosen As The Second Independent Unit Instead Of The Volt Many Absolute Measure Ments Of The Ampere And Of The Ohm Have, However, Been Made Since Gauss And Weber First Showed In 18 32 That A System Of Absolute Units Is Possible These Determinations, Having Been Made At Different Times And At Different Places, Can Be Com Pared Only By Comparing The Various Concrete Standards Adopted At The Different Times As There Can Be No Concrete Standard Ampere, Two Expedients Have Been Adopted For Preserving The Results Of The Absolute Measurement Of Current That Most Favored In The Past Is To Determine The Mass Of Silver Deposited Per Second In A Silver Voltameter By A Current Of One Ampere The Other, Which In Many Cases In The Past Served As Intermediary Between The Absolute Determination And The Silver Voltameter Measurement, Is To Determine The Electromotive Force Of A Certain Standard Cell In Terms Of A Standard Of Resistance And The Absolute Ampere Determined By The Balance.About The PublisherForgotten Books Publishes Hundreds Of Thousands Of Rare And Classic Books Find At Www.forgottenbooks.comThis Book Is A Reproduction Of An Important Historical Work Forgotten Books Uses State Of The Art Technology To Digitally Reconstruct The Work, Preserving The Original Format Whilst Repairing Imperfections Present In The Aged Copy In Rare Cases, An Imperfection In The Original, Such As A Blemish Or Missing Page, May Be Replicated In Our Edition We Do, However, Repair The Vast Majority Of Imperfections Successfully Any Imperfections That Remain Are Intentionally Left To Preserve The State Of Such Historical Works.
