\(\lambda_{\infty}=\lambda_{a}+\lambda_{c}\)
where, \(\lambda_{a}=\) equivalent conductance of the anion \(\lambda_{c}=\) equivalent conductance of the cation Each ion has the same constant ionic conductance at a fixed temperature, no matter of which electrolyte it forms a part.

${Cu}({s})\left|{Cu}^{2+}({aq})(0.01 {M}) \| {Ag}^{+}({aq})(0.001 {M})\right| {Ag}({s})$ કોષ માટે ,કોષનો પોટેન્શિયલ $=.....\times 10^{-2} {~V}$
[ઉપયોગ : $\frac{2.303 {RT}}{{F}}=0.059$ ]
$Cu^+_{(aq)} + e^- \rightarrow Cu_{(s)}$ માટે વિધુતધ્રુવ પોટેન્શિયલ અનુક્રમે $+ 0.15\, V$ તથા $+ 0.50\, V$ છે. $E^o_{Cu^{2+}/Cu}$ ....... $V$ થશે.
