1. The problem statement, all variables and given/known data "A series combination of capacitors must always be smaller than the smallest individual capacitor." This is the statement that I am trying to validate, but I am stuck. 2. Relevant equations 3. The attempt at a solution I know that if you have a circuit that consists of a cell and a number of capacitors in parallel, the overall effect due to the 'inside' plates neutralising each other, is that of one capacitor with a large plate separation. This large plate separation is what causes the equivalent capacitance to be lower than the sum of it's parts, but I don't understand how I can show that this value must be smaller than that of the smallest capacitor in the circuit. I can show that it is the case for specific examples, but not a general case. Thanks for any help you can give, Jacob.
