I am watching this video where the guy deducts the voltage across the capacitor during the transient phase.
There is an integral, in the middle of the equations. The guy integrates that and there is no constant of integration after that.
This is not just this guy, I am not aware of any of the capacitor/inductor formulas where the tutor considers them.
Why is that? Why can you simply ignore the constant of integration for all these equations?
