The ideal capacitor DC analysis shows the time constant to be a function of the load resistance and capacitance.

Since the load resistance will be constant during discharge, is there any research on modulating the capacitance with a feedback to maintain the current? This may be naive/illogical to the practicing engineers who know the in depth physics... but as a novice I wish to know.

  • \$\begingroup\$ Just replace the capacitor with a short circuit to get what you want. If you feel that is not what you want then you need to put more detail in your question. \$\endgroup\$ – Andy aka Apr 27 at 8:51
  • \$\begingroup\$ i expected a good comment,u r asking me to discharge the capacitor or remove an energy source with a short? i dont feel your reply to be anywhere a reply but a mockery.And i am not that much novice..m too a practicing engineer but in a different segment of electronics \$\endgroup\$ – shubhayan de Apr 27 at 11:46
  • \$\begingroup\$ If you want \$\color{red}{\text{to maintain the current}}\$ you must short the capacitance. \$\endgroup\$ – Andy aka Apr 27 at 11:52

    \$\begingroup\$ Then you need to show your circuit proposal and not expect people to guess what you are talking about. Put your circuit proposal into the question. \$\endgroup\$ – Andy aka Apr 27 at 11:58

    \$\begingroup\$ Nobody is going to try and remake your schematic in their mind's eye. This is why we use schematics - values and component names are important for references when making answers or observations. \$\endgroup\$ – Andy aka Apr 27 at 12:10
