Learn Moreand then solve. Clearly, this does not depend on the applied voltage since we''re interested in a dimensionless number - the fraction of the final voltage rather than the absolute voltage. For a simple exercise, how long does it take for the capacitor voltage to reach $(1 - 1/e) approx 63.2%$ of the final value?
Learn MoreMultiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.
