4 · This is consistent with expectation: observe that (Q(t to infty) to CV). That is, in steady state the capacitor has charged until the voltage across the capacitor completely opposes the voltage of the battery that is drives the current, so current no longer flows in steady state: a fully charged capacitor acts as an open circuit.

When a fully charged capacitor is discharged through
Question: When a fully charged capacitor is discharged through a single resistor, with no other components in the circuit, which of the following is fulse?The current in the circuit takes an infinite time to reach zero.The capacitor voltage decreases by half after a time equal to RC.The current in the capacitor is equal to the current in the resistor.The electrical
14.6: Oscillations in an LC Circuit
When fully charged, the capacitor once again transfers its energy to the inductor until it is again completely discharged, as shown in Figure (PageIndex{1d}). Then, in the last part of this cyclic process, energy flows back to the capacitor, and the initial state of the circuit is restored.
Does a capacitor ever get fully charged?
there is ever-present and random noise and, after some number of time constants, the ''charge current'' predicted by the simple model is below the noise floor. Since the capacitor goes from zero charge to better than 99% charged in $5tau$, we typically use this as the time required to ''fully'' charge the capacitor.

In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator (Figure (PageIndex{2})) delivers a large charge in a short burst, or a shock, to a person''s heart to correct abnormal heart rhythm (an arrhythmia). A heart attack can arise from the onset of fast, irregular beating of the …
