Customer ServiceStrictly speaking, a capacitor is not a short connection since its terminals are separated by an insulator. It rather behaves as a short connection with respect to the voltage drop across it. Both they - a piece of wire and a
Customer ServiceStrictly speaking, a capacitor is not a short connection since its terminals are separated by an insulator. It rather behaves as a short connection with respect to the voltage drop across it. Both they - a piece of wire and a discharged capacitor (at startup), have zero voltage drop across themselves; so the current is maximum.

(A short circuit) As time continues and the charge accumulates, the capacitors voltage rises and it's current consumption drops until the capacitor voltage and the applied voltage are equal and no current flows into the capacitor (open circuit). This effect may not be immediately recognizable with smaller capacitors.

As time progresses and the capacitor charges, current through the cap decreases as it becomes more and more difficult to force still more charge onto its plates.
When a DC voltage is applied across an uncharged capacitor, the capacitor is quickly (not instantaneously) charged to the applied voltage. The charging current is given by, When the capacitor is fully charged, the voltage across the capacitor becomes constant and is equal to the applied voltage.
It doesn't act like a short circuit for a current impulse. Here's the equation that defines the ideal capacitor: iC(t) = C ⋅ d dtvC(t) Applying the Laplace transform to this equation (assuming zero initial conditions) yields IC(s) = sC ⋅ VC(s) The Laplace transform for the unit impulse is δ(t) ⇔ 1
