When a capacitor has an initial voltage and then starts to charge, the equations for modeling this need a small modification. This video shows you that modification.

If you need to review capacitors before learning how to analyze capacitors with an initial voltage, check out my website:
electronx.ca/education/dc-circuits/dc-chapter-13
electronx.ca/education/dc-circuits/dc-chapter-16
Or this capacitor playlist:
youtube.com/playlist?list=PLQlQ509bAPoFxxwePV0EyCOnfsoTu8YQP

You'll find all the basics about capacitors, as well as videos and a textbook chapter to help you understand what is happening and how to analyze charging and discharging capacitors.
