Two parallel plane sheets 1 and 2 carry uniform charge densities $σ_{1}$ and $σ_{2}$ (see Fig. 20.8). The electric field in the region marked I is $(σ_{1} > σ_{2})$ . (Consider the right direction as the positive direction)

Current I is flowing through two materials having electrical conductivities

where

σ_{1} > σ_{2}

, then total amount of charge at the junction of materials is
