Electrons flow in the opposite direction.
In a standard galvanic cell using zinc and aluminum, the zinc metal will act as the anode and the aluminum metal will act as the cathode. Zinc will undergo oxidation at the anode, releasing electrons which flow through the external circuit to the cathode where aluminum will undergo reduction. This flow of electrons creates an electrical current.

There is no difference between a galvanic cell and a voltaic cell - they are two terms that refer to the same type of electrochemical cell that converts chemical energy into electrical energy. Both terms are commonly used interchangeably in the field of chemistry.

Electrons flow in the opposite direction.
In a galvanic cell with silver and nickel electrodes, nickel is oxidized at the anode. During oxidation, nickel atoms lose electrons and become Ni2+ ions, contributing to the flow of electrons in the cell. Silver acts as the cathode where reduction reactions take place.
the nickel metal
In a standard galvanic cell using zinc and aluminum, the zinc metal will act as the anode and the aluminum metal will act as the cathode. Zinc will undergo oxidation at the anode, releasing electrons which flow through the external circuit to the cathode where aluminum will undergo reduction. This flow of electrons creates an electrical current.
In a galvanic cell with silver and nickel electrodes, the nickel electrode will be oxidized. Oxidation occurs at the anode, where electrons are released as nickel atoms lose electrons and form nickel ions. Silver ions from the other electrode will capture these electrons as the reduction reaction occurs at the cathode.

The voltage of a galvanic cell made with silver and nickel will depend on the specific conditions of the cell, such as the concentrations of the electrolytes and the temperature. Typically, a cell made with silver and nickel could have a voltage range between 0.8 to 1.0 V.
