How is the voltage predicted ?

Choosing electrodes for a galvanic cell, what is the way to predict the voltage such cell will generate ?

 

By looking at the differential in a galvanic series table like ----> http://l-36.com/corrosion.php

Which would be +0.25V (Zn) and -1V C) yielding 1.25 Volts ?

 

Or by looking at the differential in an electrochemical series table like ----> http://www.chemistry-assignment.com/electrochemical-series

Which would be -0.76V (Zn) and as C is unlisted there, say +0.34V (Cu) yielding 1.1 Volts ?

 

Or some other way ?

 

Would choosing instead, Zn and stainless 316 yield about the same potential of 1.2 Volt ?
