उत्तर
The electrode systems having positive values of standard electrode potentials act as cathode when connected to a standard hydrogen electrode.
Explanation:
Electrodes with positive standard electrode potentials have a greater tendency to gain electrons (i.e., get reduced), so they act as cathodes when paired with the standard hydrogen electrode (SHE), which has E° = 0 V.
