"in serise"! why they are connected in parallel as one capacitor

yes it can be done by switching and assume that this capacitors are ideal and they are connected to a resistance R

hi i need an equation which can describe the charging time of two parallel capacitors one of them is %50 charged and if i have a capacitor which is always charged from 50% to 100% and never fully discharged will it have a different impedance than the fully charged/discharged capacitor?

Sorry my quistion was not clear.I am tring to make something like ultrasound sonar but uses sounds created in the body .Heart beat is about 2Hz or grater but not in the audo rang but you can lesten to this sound.I think that this sound is created by the flow of blood

hi i was trying to prepare for a project based on passive sensing of sound waves By using natural sound created naturally by blood flow may be turbulence flow of blood in blood vessels So i want to know how to calculate the frequency ranges which can be generated in the human body
