WebI would immediately understand that inequality if we were talking about the initial stages of vacuum diode operation, when the space charge is still being accumulated, i.e. when emitted electrons leave the cathode and just stay in space charge area around it. Web5. mar 2024 · The electric field, however, is now only E = V / d 2 and D = ϵ 0 V / d 2. But Gauss’s law still dictates that D = σ, and therefore the charge density, and the total charge on the plates, is less than it was before. It has gone into the battery. In other words, in doing work by separating the plates we have recharged the battery.
