(5 pts) What is your value for ? Be sure to include sign if appropriate.

(3 pts) Shown here is a capacitor array connected to an EMF source . The capacitors have the values  = μF, = μF, = μF, = μF, and = μF. A voltmeter is measuring the potential at point with respect to point to be = V. What is the equivalent capacitance between point and point in units of μF?

What is the equivalent resistance between points A and B in the figure when =  Ω? Please enter your answer in Ω.

How long will it take a charged 80 μF capacitor to lose 20% of its initial energy when it is allowed to discharge through a 45 Ω resistor?

(3 pts) You now have 3 equations for 3 unknowns (, , and ). You now need to solve. You have already entered your value for above. Give some details for how you found this value here.
