The switch in the figure is closed at t = 0 when the current I is zero. When I = 15 mA, what is the potential difference across the inductor?
 
   

   
  a.
  240 V
   
  b.
  60 V
   
  c.
  0
   
  d.
  180 V
   
  e.
  190 V

Question 2

Before the switch is closed in the figure, the potential across the capacitor is 200 V. At some instant after the switch is closed, the instantaneous current is 0.70 A. What is the energy in the capacitor at this instant?
 
   

   
  a.
  49 mJ
   
  b.
  31 mJ
   
  c.
  80 mJ
   
  d.
  0.13 J
   
  e.
  62 mJ
