How to solve the weather resistance problem of capacitors
Capacitors
A charged capacitor represents a value of 1, while a discharged capacitor represents a value of 0. An often cited value in the semiconductor industry is that DRAM capacitors should have a minimum capacitance of 30 fF. An electrical engineer wishes to design a DRAM chip composed of 30 fF capacitors with a plate separation of 100 nm.

Capacitive Reactance
1A. For Series Capacitors. When capacitors are connected in series, the total capacitance is less than any one of the series capacitors'' individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacing of the individual …

Resistance of capacitors
A capacitor has an infinite resistance (well, unless the voltage gets so high it breaks down). The simplest capacitor is made from two parallel plates with nothing but space in between - as you can guess from its electronic symbol. In a DC circuit, a capacitor acts as an open circuit and does not permit current to pass.

Capacitors — Collection of Solved Problems
Charges on capacitors in series are equal to each other and in this case also equal to the total charge. Therefore the charge on the third capacitor is equal to the total charge. If we know the charge, we can evaluate the voltage on the third capacitor. Voltages on both capacitors connected in parallel are the same.
