energy stored in a capacitor (in series combination and parallel combination)
Asked by ap996969 | 19 Feb, 2019, 12:20: AM
answered-by-expert Expert Answer
if two capacitors C1 and C2 are connected in parallel, equivalent capacitance  Ceq  = C1 + C2
 
if two capacitors C1 and C2 are connected in series, equivalent capacitance Ceq  = begin mathsize 12px style fraction numerator C subscript 1 C subscript 2 over denominator C subscript 1 plus C subscript 2 end fraction end style
Energy stored in capacitor E = begin mathsize 12px style 1 half C V squared end style
In case of series or parallel combination we substitute the equivalent capacitance in the above expression for energy stored

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?
