(6%) Problem 3: A bank of batteries, total emf & = 4.5 V, is connected with resistor R = 180 k$2, capacitor C = 680 pF, and two-pole switch S as shown. The switch is initially set to point b R 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.

A 25% Part (a) The switch is disconnected from point b and connected to point a. What will happen to the voltage across the capacitor? Grade Summary The voltage will increase linearly with time. Deductions 0% The voltage will immediately drop to zero. Potential 100% The voltage will immediately rise to &. Submissions The voltage will not change. Attempts remaining: 6 The voltage will increase exponentially with time. (16% per attempt) detailed view The voltage will drop linearly with time. The voltage will drop exponentially with time. Submit Hint Feedback I give up! Hints: 0 for a 0% deduction. Hints remaining: 0 Feedback: 2% deduction per feedback. A 25% Part (b) Calculate the time constant, t(in seconds), for this circuit. A 25% Part (c) Determine an expression for the charge on the capacitor as a function of time, q(t), in terms of parameters given in the original problem statement. 25% Part (d) Calculate the voltage drop across the capacitor (in volts) at time t = 140 us after the switch is connected to point a.
