8.3: Initial and Steady-State Analysis of RC Circuits
When analyzing resistor-capacitor circuits, always remember that capacitor voltage cannot change instantaneously. If we assume that a capacitor in a circuit is not initially charged, then its voltage must be zero. The instant the circuit is energized, the capacitor voltage must still be zero.
8.4: Energy Stored in a 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 heart—called cardiac or ...

Connecting a charged capacitor to an uncharged capacitor
When we say that a capacitor is uncharged it means that the net charge on each plate of the capacitor is zero ie equal numbers of positively charged ions and negatively charged electrons. The charged capacitor also has a net zero charge it just so happens that there is a net surplus of electrons on one plate and an equal net deficit of ...
