$\underset{1\mathrm{m}\mathrm{o}\mathrm{l}}{\mathrm{C}{\mathrm{u}}^{2+}}+\underset{2\mathrm{F}}{2{\mathrm{e}}^{-}}\to \mathrm{C}\mathrm{u}$
1 mole$\mathrm{C}{\mathrm{u}}^{2+}=2$equivalent of$\mathrm{C}{\mathrm{u}}^{2+}$
or 2 equivalent of$\mathrm{C}{\mathrm{u}}^{2+}$requires = 2F
So 4 equivalent of$\mathrm{C}{\mathrm{u}}^{2+}$will require = 4 F
