When is the potential difference V= e+ ir?

answered-by-expert Expert Answer
When the cell is charged by passin external current , emf of the cell is added by potential drop across internal resistance.
 
Hence Terminal voltage will be  ( e + i R ) , where e is emf of cell , i is the current passing through cell while it is getting charged
 
and R is its internal resistance

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
