APPENDIX C
PC.1 Because the capacitor voltage is zero at
t
= 0, the charge on the
capacitor is zero at
t
= 0. Then using Equation 3.5 in the text, we have
PC.2 Refer to Figure PC.2 in the book. Combining the 10-Ω resistance and the
PC.3 The equivalent capacitance of the two capacitors in series is given by
