WebNov 25, 2013 · This is an ideal open circuit; the current is zero for any voltage across. Now, consider the I-V characteristic for an ideal resistor with a small resistance: As R → 0, the slope approaches infinity, i.e., the I-V characteristic becomes vertical through the origin. This is an ideal short circuit; the voltage is zero for any current through.
Web(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.
