For the circuit shown, what is the rate of change of the current in the inductor when the current in the battery is 0.50 A?
 
   

   
  a.
  600 A/s
   
  b.
  400 A/s
   
  c.
  200 A/s
   
  d.
  800 A/s
   
  e.
  500 A/s

Question 2

A bolt of lightning strikes the ground 200 m from a 100-turn coil oriented vertically and with the plane of the coil pointing toward the lightning strike. The radius of the coil is 0.800 m and the current in the lightning bolt falls from 6.02  106 A to zero in 10.5 s. What is the voltage induced in the coil over this time period? A question for future electrical engineers: is there any way to get lightning to strike repeatedly at the same point?
