The voltage of a galvanic cell is the difference between the half cell potentials for the two reactions. For silver and nickel, this is about 1 volt.

Two electrodes in electrolyte solutions
A voltaic battery is also known as a voltaic pile, which is a set (or pile) of galvanic cells linked together in series to create a larger voltage than could be generated by a single galvanic cell. Therefore a voltaic cell would simply be one element of the pile which is also one galvanic cell.
.. A redox reaction at two electrodes causes electrons to flow.
Mg(s)
The voltage of a galvanic cell is the difference between the half cell potentials for the two reactions. For silver and nickel, this is about 1 volt.
