[QUOTE="Ivan Antunovic, post: 5453949, member: 573634"] [h2]Homework Statement [/h2] Review of the current field junction at the crossover of two linear surface , such as Figure 6. The ratio of the relative permitivity environment is εr2 / εr1 = 3. The current density vector J1 in the he first environment , closes with the normal to the split surface angle α1 = π / 6, and the intensity of this vector is J1 =1μA/mm^2 . On crossover surface, there is no surface free of charge. Determine the intensity of vector J2 in the 2nd environment [ATTACH=full]187231[/ATTACH] [url=http://postimage.org/]photo hosting[/url][h2]Homework Equations[/h2] J = σE tan(α1)/ tan(α2) = ε1 / ε2 [h2]The Attempt at a Solution[/h2] [ATTACH=full]187232[/ATTACH] [url=http://postimage.org/]pic upload[/url] [/B] I don't have relation between σ1 and σ2 , so I don't know how to solve this. Correct solution is d) 1.732 μA/mm^2 [/QUOTE]
