Theory of drop growth in presence of external electric field and pollutant particles has been applied to water vapour condensation. In presence of electric field, Helmholtz free energy of formation of water molecule about a critical nucleus is found to be much less than that in absence of the electric field. We see that for vapour just saturated with respect to water, the energy of the nucleus formation rapidly increases with size as r2wc. The observations suggests that nucleation rate is extremely sensitive to supersaturation ratio, since the term in the exponent varies as S-2v,w. Since in presence of ions and electric field a small value of electric field is comparable to very high supersaturation ratio to get a nucleus of given size under similar conditions of temperature.
