WebOct 9, 2016 · In fact, in many problems given a free charge density, you can use the formula to obtain the $\mathbf{D}$ conveniently. When currents exist, there could be additional free charge at the boundary between dielectrics (to satisfy the continuity of currents), which means $\sigma_0$ is not necessarily 0 even there are only dielectrics, … Web3 Answers. Sorted by: 3. +50. I think you can estimate the maximal surface charge density as follows. The energy needed to remove an electron from a solid to a point immediately outside the solid is called work function W. For aluminum W is about 4.06 − 4.26 eV. times of india chennai news https://jackiedennis.com
