Solution: a) Use component values from Appendix H to create

Chapter 7, Problem 7.59

(choose chapter or problem)

a) Use component values from Appendix H to create a first-order RC circuit (see Fig. 7.21) with a time constant of 250 ms. Use a single capacitor and a network of resistors, if necessary. Draw your circuit. b) Suppose the capacitor you chose in part (a) has an initial voltage drop of 100 V.At t = 0,a switch connects a current source with a value of 1 mA in parallel with the capacitor and equivalent resistance. Write an expression for the voltage drop across the capacitor for t 0. c) Using your result from part (b), calculate the time at which the voltage drop across the capicitor reaches 50 V
