really awesome.. waiting for wonderful circuit theory 2 🥰

one could argue that the voltage source has the same behaviour as a capacity C1 of earlier lesson where 2 capacitors were involved.
The voltage source has the behaviour of a Capacity C1 that cannot be decharged, or otherwise said is very very large
this results into Vout (at t = infinite) = V1* C1 / C1 + C2 with very big C1 this becomes Vout (at t = infinite) = V1

I do not understand why there is a multiplication by a unit step function can someone please clarify. (29:00)
