What is the voltage of a galvanic cellmade with silver and nickel?

The voltage of a galvanic cell made with silver and nickel will depend on the specific conditions and concentrations of the electrolytes used. However, the standard electrode potentials for the silver and nickel electrodes are +0.80 V and -0.23 V, respectively. So, under standard conditions, the cell potential would be 1.03 V.
