What is electric file strength?

The electric field strength is defined as the ratio of electric force and charge.

The electric field strength is found as;

[tex]\rm E = \frac{I \rho }{A} \\\\ \rm E = \frac{20 \times 1.68 \times 10^{-8} }{ (0.6385 \times 10^{-6}} \\\\ E= 0.5262 \ V/m[/tex]

Hence, the electric field strength will be 0.6252 V/m.
