a)Fe serves as the cathode while Zn serves as the anode. b)Ag is the cathode, and Sn is the anode. c) Zn is the anode and Cu is the cathode.
d) Al is the cathode and Sn is the anode.
An electrical device with polarisation has an electrode called an anode through which regular current flows. The cathode, an electrode of the device through which regular current exits the device, is in contrast to this. For "anode current into the device," the acronym ACID is frequently used. Since electrons move in the opposite direction to conventional current, which is the flow of positive charges in a circuit, (negatively charged) electrons flow out of a galvanic cell's anode and into an external circuit that is linked to the cell. For instance, the anode is located at the end of a household battery that is marked with a "-" (minus).
In both galvanic and electrolytic cells, the oxidation reaction takes place at the anode electrode.
