The voltage of an electrolytic cell with nickel and copper electrodes depends on the specific electrolyte used and the concentration of the solutions. Typically, nickel and copper electrodes can have a cell potential of around 0.3 to 0.5 volts when considering their standard reduction potentials. However, in an electrolytic cell, an external voltage is applied to drive the non-spontaneous reactions, which may exceed this value. The actual voltage required will depend on factors such as electrode surface area, temperature, and the specific setup of the cell.

In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.

Use two electrodes of dissimilar metal (eg. nickel and copper). Stick them in the bannana. A small voltage will be developed across the two electrodes, due to the mild acid in the bannana. Most fruits (and seeds) will work this way, citrus fruits are better, due to the strength of the acid.
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.
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
It is made of copper and nickel. A 1949 NICKEL is made from copper & nickel.
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
