but sir,
if we take from the perspective of time response, t=0+ represents the transient response , and the 1.294 v is the steady state value. so if v(t=0+ )=1.294 V instead of 0.8 V, it has bypassed transient and reached steady state?
i am really confused.
There are no resistors in the circuit to delay the steady state. So as it is, v(t=0+) should give 1.294V. Practically there will be a small interval between 0.8V and 1.294V due to the time constants determined by capacitors and the ESR of the caps and wiring resistance.
