A series circuit consists of a 0.55-H inductor with internal resistance of 8.0 Ω connected in series with a 4.0-Ω resistor, an open switch, and an ideal 12-V battery.   (a) When the switch is closed, what is the initial current through the 4.0-Ω resistor?  [currinit][currunits] (b) What is the current through the 4.0-Ω resistor a very long time after the switch is closed?  [currfin][currunits2]

Recall the two algorithms to compute shortest paths in a graph via dynamic programming: Bellman-Ford (BF) and Floyd-Warshall (FW). Check all true statements:

Design an algorithm to solve the following problem. Input: a directed graph G=(V,E). Output: the number of vertices that fall in at least one cycle.  

For the circuit shown in the figure, the inductors have no appreciable resistance and the switch has been open for a very long time. (BONUS 3pts) After the switch has been closed and left closed for a very long time, what is the potential drop across the 60.0-Ω resistor? Explain. [Vlate][Vlateunits]

One of the major differences between parent education and therapy is:

Which of the following echoes will always be absent in an axial length scan of an aphakic patient?

Which of the following describes the threshold for VF stimuli when testing?

When the electric field is zero at a point, the potential must also be zero there.    

For the circuit in problem 19: an LRC series circuit containing a resistance of 11.0kΩ a capacitance of 2.0μF and an inductance of 24.0H, what is the peak current and voltage through each of the components when operating at the frequency to minimize the impedance? (Note: If you couldn’t find or don’t have the equation for that frequency, you can still get most of the credit for finding these values for some frequency of your choosing, provided you say that’s what you’re doing in your work.)
