Hello, I understand fairly well how to calculate the integral and write it in terms of unit step functions, but I am unsure of how I would go about making a hand-written plot of the result. If possible, would you please explain how you'd go about the process of plotting/graphing the result? (preferably not with MATLAB)
A= 20
B=10
PLEASE ANSWER QUICKLY
9) Switch S1 closes at t=0.
What is the final voltage across the capacitor? What is the current through the capacitor at t=0? How long does it take the capacitor to reach it’s final voltage?
