WebSep 4, 2014 · Now imagine sliding the dielectric out of the plates in the direction that the plates have length l by a distance x. The idea is to find the force on the dielectric. You can do this for two cases - constant charge and constant voltage. Both give the force as. F=-ε 0 XwV 2 /2d along the x direction where V is the p.d between the plates. WebMar 5, 2024 · The charge held by the capacitor is then. Q = [ ϵ a 2 − ( ϵ − ϵ 0) a x d] V. If the dielectric is moved out at speed x ˙, the charge held by the capacitor will increase at a rate. Q ˙ = − ( ϵ − ϵ 0) a x ˙ V d. (That’s negative, so Q decreases.) A current of this magnitude therefore flows clockwise around the circuit, into the ...

Dielectrophoresis (DEP) is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. This force does not require the particle to be charged. All particles exhibit dielectrophoretic activity in the presence of electric fields. However, the strength of the force depends strongly on the medium and particles' electrical properties, on the particles' shape and size, as well as on the frequency of the electric field. Consequently, fields o…
