Capacitor Transient Response | RC and L/R Time Constants | Electronics Textbook

A fully discharged capacitor, having a terminal voltage of zero, will initially act as a short-circuit when attached to a source of voltage, drawing maximum current as it begins to build a charge. Over time, the capacitor''s terminal voltage rises to meet the applied voltage from the source, and the current through the capacitor decreases correspondingly.
