1. The problem statement:
What is the value of capacitance needed in Fig. 1 so that the voltage across the capacitor never exceeds (a) 200 V, (b) 20 V, and (c) 2 V ?
This is the Circuit
Homework Equations
Vc(0-) = 0V
Vc(0+) = 150V
ic = c v'
vc(t) = final + [initial -...
Need Help with a couple diff eq problems:
2.) show y=cx^2 - x is a solution of xy' - 2y + x =0
I was trying to separate the variables so i could integrate but i cannot get it to work out.
I have tried so many things from adding 2y to both sides and and multiply by the inverse dx/dy. but...
