Consider the following RC circuit. The capacitor has an initial charge q0 such that it opposes the flow of charging current:
The response of the circuit i(t) will be
1
\(\left( \frac{E}{R}-\frac{{{q}_{0}}}{RC} \right){{e}^{-\frac{t}{RC}}}\)
2
\(-\frac{{{q}_{0}}}{RC}{{e}^{-\frac{t}{RC}}}\)
3
\(\frac{E}{R}\;{e^{ - \frac{t}{{RC}}}}\;\)
4
\(\left( {\frac{E}{R} + \frac{{{q_0}}}{{RC}}} \right){e^{ - \frac{t}{{RC}}}}\)
