Web12 apr. 2024 · The capacitor energy is. U = Q 2 2 C = Q 2 2 ( L ϵ A + z ϵ 0 A). Finally, the force is found upon taking the derivative, keeping the charge Q constant: F = − d U d z = − Q 2 2 ϵ 0 A. The negative sign indicates that the force is attractive, i.e. in the direction opposite to that you moved the plate in. Web12 sep. 2024 · ϵC − q ϵC = e − t / RC. Simplifying results in an equation for the charge on the charging capacitor as a function of time: q(t) = Cϵ(1 − e − t RC) = Q(1 − e − t τ). A graph of the charge on the capacitor versus time is shown in Figure 10.6.2a . First note that as time approaches infinity, the exponential goes to zero, so the ...
