Input AC voltage, b. Load current, c.
The first bullet is correct, the outer shell does not contribute. This easily follows from Gauss'' law. For this you use the fact that the electric field must be radial and any cylinder inside the cylindrical shell does not enclose the charge density $-lambda$.You might think that close to the negatively charged shell there is an additional electric field pointing in the same direction ...

Calculation of the nominal value of the capacitor by symbolic marking The capacitors are marked with numbers and letters that indicate the nominal value of the capacitor. This calculator allows you to calculate the nominal value for various capacitors: film, ceramic, tantalum and mica.
The OP''s original post has formulae reversed. The ripple for half-wave rectification is larger than that for full wave. Easy to think about: if you charge a cap with a half a wave of voltage and current, it will discharge less if you have another charging half wave right after the first, and more if you have to discharge the cap another half wave with no input.
Capacitor value should be large enough that it can provide enough voltage(+2 volts means 7v for 7805) to the regulator IC, means voltage across capacitor should not go below 7v. I have found a article where Capacitance calculation has been explained well,it may be useful for others, Capacitance calculation for 5v DC. Thanks
To estimate the ESR for your capacitors, I would look up the tan(δ) value, finding 0.12 at 100 Hz, and I would calculate the reactance at 100 Hz, ignoring parasitic inductance and ignoring the fact that it''s nonlinear.

Calculate the capacitance of the capacitor. Then the value of the capacitor consisting of two plates separated by air is calculated as 0.221nF, or 221pF.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
Capacitor power (Pc) represents the magnitude of this reactive power exchange. Capacitor power, P c(W) in watts is calculated by the product of current running through the capacitor, I c(A) in amperes and voltage running through the capacitor, V c(V) in volts.. Capacitor power, P c(W) = I c(A) * V c(V). P c(W) = capacitor power in watts, W.. V c(V) = voltage in volts, V.
