I respectfully will take in account that the most basic is determined by the characteristics of the power output components, for delivering the power you require, so, you will find out the output secondary voltages must be applied to that components to give the o/power.
Normally for that power...
Hi, I may suggest you to find out how this zener diode is connected, if as a reference voltage, or as a overvoltage shortcircuit protector, (the second if the Z pin goes to the o/p voltage, and the back of the arrow goes to ground).
The answer that Bill gave you is correct, you can not convert either from capacitor to resistor or from resistor to capcitor, but you can know the capacitive reactance which is a sort of resistive capacitance, but only works with ac, and is frequency dependent.
There is quite a lot of theory on...
