Electric Fields and Capacitance | Capacitors | Electronics Textbook
If a source of voltage is suddenly applied to an uncharged capacitor (a sudden increase of voltage), the capacitor will draw current from that source, absorbing energy from it, until the capacitor''s voltage equals that of the source. Once the capacitor voltage reaches this final (charged) state, its current decays to zero.
