Just need part D. Answer is 6.725, just don't know how to get there. l Help Practice Problems 7 Resistance, RC-Circuits Begin Dat AM ms 7 Resistance, RC Circuits Begin Date: 3/1/2016 12:00-00 AM-Due Date: 5/7/2016 12 00:00 AM End Date: 5/7/2016 12:0000 (10%) Problem 8: A bank of batteries, total emf ·7.5 V, is connected with resistor R = 150 kS2, capacitor C = 470 pF, and two-pole switch S as shown. The resistor R- 150 k2, capacitor C-470 pF switch is initially set to point b so that the resistor and capacitor are in series. The switch is left in this position for a sufficiently long time so that the capacitor is completely discharged Randomized Variables C-470 pF r 160 us Otheexpertta.com a. What will happen to the voltage across the capacitor? se 25% Part (a) The switch is disconnected from pont b and connected to port S8 25% Part (b) Calculate the time constant, (in seconds) for this circuit 25% Part (c) Determine an expression for the charge on the capacitor as a function of time, q(f) in terms of parameters given in the original problem statement Final Grade Student Answer Correct Answer No Answer Given 0% Grade Detail Correct Feedback Final Answer Credit 0% Accessing Correct Answer Penalties 100% Submission History Answer Hints Feedback Totals 0%|0% Totals 25% Part (d) Calculate the voltage drop across the capacitor (in volts) at trne t = 160 s after the switch is connected to point a

Explanation / Answer

for Volatge drop use thw equation

V = Vo (1 - e^-t/RC)

V = 7.5 * (1- e^-(160e-6)/(150e3* 470 e -12)

V = 6.72 Volts
