Part A: The current is decreasing at a constant rate didt$=0\mathrm{.}018$As

Find the self$-$induced emf. VL $=[$ Select $]["1\mathrm{.}26","4\mathrm{.}68","3\mathrm{.}73","5\mathrm{.}59","2\mathrm{.}65","7\mathrm{.}32"]$ x $10-3$ V

Which end of the inductor is at a higher voltage a or b$?[$ Select $]["$end a$",$ "end b$",$ "Bothe ends are at the same voltage", "Not enough information to determine"$]$

Part B: Suppose now that the voltage difference between points a and b is Vab $=1\mathrm{.}04$V with point a at higher voltage than point b$.$ The current is changing again at a constant rate.

Is the current now increasing or decreasing? $[$ Select $]["$Increasing$",$ "Decreasing", "The Current is Constant", "Not enough information to determine"$]$

If the current at t $=0$ is $12$A what is the current at t $=2\mathrm{.}0$ s$?[$ Select $]["0$ A$","1$ A$","2$ A$","3$ A$","4$ A$","5$ A$","6$ A$"]$
