Given: r = 0.4 mm = 0.4 × 10-3 m, I = 2 A
To find: Current density (J)
Formula: J = \(\frac{I}{A}\)
Calculation: From formula,
J = \(\frac{2}{3.142\times(0.4)^2\times10^{-6}}\)
= 3.978 × 106 A/m2
rausch’s law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations.
The molar conductivity of a solution...
