Please sketch and label the step input response of Vc(t). Thank you so much!

(i) Referring to the R-C circuit shown in Figure 2.0a, assume the switch has been in
position "x" long enough so that the capacitor is fully discharged. At time t = 0, the
switch is abruptly moved to position “y” connecting the circuit to the voltage source,
thereby creating a step-input voltage of Vp. It stays in this position long enough for the
capacitor to be fully charged and beyond. Recall, since the voltage across the capacitor
does not change instantaneously, then Vc(t) becomes a more convenient variable to
characterize the transient response in the "charging" phase than Ic(t).
For the above stated conditions, sketch & label the step-input response of Vc(t) and
prove that this charging transient response can be expressed as:
Vc(t) = Vp(1 e) where T = RC
