Quizplus · Accepted Answer

The capacitor in an RC integrator charges towards the input voltage but never fully reaches it within a finite time. However, after six time constants, it will have charged to about 99.75% of the input voltage, which for practical purposes, can be considered as the input voltage itself, hence 10 V.
