Over time, the capacitor voltage will rise to equal battery voltage, ending in a condition where the capacitor behaves as an open-circuit. Current through the circuit is determined by the difference in voltage between the battery and the capacitor, divided by the resistance of 10 kΩ.
This isn't physically possible, so a capacitor's voltage can't change instantaneously. More generally, capacitors oppose changes in voltage|they tend to \want" their voltage to change \slowly". An inductor's current can't change instantaneously, and inductors oppose changes in current.
Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going in the negative side and out the positive side, like a resistor).
A capacitor's ability to store energy as a function of voltage (potential difference between the two leads) results in a tendency to try to maintain voltage at a constant level. In other words, capacitors tend to resist changes in voltage drop.
When a capacitor is faced with a decreasing voltage, it acts as a source: supplying current as it releases stored energy (current going out the negative side and in the positive side, like a battery). The ability of a capacitor to store energy in the form of an electric field (and consequently to oppose changes in voltage) is called capacitance.
If a capacitor is introduced into this circuit, it will gradually charge until the the voltage across it is also approximately 5V, and the current in this circuit will become zero. What is now preventing us from suddenly changing the voltage from 5V to let's say 10V (again like a step increase - instantaneously)?
