Hello,

The circuit attached below is from Richard Dorfs Intro to Electric Circuits book. The switch is shut for a long time and opened at t=0.

The question asks to find the i(t) across R11, which they use nodal analaysis and find it to be 66.67 - 16.666 e[tex]^{-t/120}[/tex] micro Amps, where 66.67 micro Amps is due to the 8 v source and - 16.666 e[tex]^{-t/120}[/tex] source due to the capacitor

My question is that if we use superposition instead, should the current due to the 8 v source and the capacitor be added since both send current towards R11 in the same direction?

Thank you in advance

P.S since this is more a theoretical question, i thought best i post it here other than the Homework section
