20.14 if a capacitor initially holds no charge, the voltage across it as a function of time can be computed as i(t) di 0 use matlab to fit these data with a fifth-order polynomial. then, use a numerical integration function along with a value of c= 10-5 farad to generate a plot of voltage versus time. 0.2 0.4 0.36830.3819 0.2282 0.6 0 0.2 0.8 i, 10-3 a 85 1.2 i, 10-3 a 00486 0.0082 0.1441
