I find the use of the Coulomb and ampere confusing. Is a coulomb used simply as a convenient way of saying the number of electrons (6.25^25 electrons) pass a certain point in circuit at any one time due to the pain in dealing with the large number of electrons. I know that an ampere is also c/second so why do we have the unit A(ampere) when we could just use c/s. Are there any cases where we talk about coulombs not in relation to time (for flow) and therefore need to have coulombs stand alone. Hope this makes sense. the whole idea of charge is confusing me. An electron or proton are terms that need not be used with the word charge as they are one in the same. We simply use + and - signs to say that they are different 'stuff' like a red ball and blue ball. both are balls only different colours.is this correct. would really appreciate any more clarity on this if you could (if possible). kind regards chris
