The following circuit is used by a biology student to study "frog kick." She noticed that the frog kicked a little when the switch was closed but kicked violently when the switch was opened. Model the frog as a resistor (Rfrog = 1000N). Assume that switch has been closed for a long time. a) Compute the initial inductor current under DC conditions. b) At t = Os the switch is opened. Compute inductor current for t > 0. c) What is voltage applied to frog for t 2 0? What could be a possible reason for the frog's violent kick? Switch 50 2 Frog + 12 V 2 H all

The following circuit is used by a biology student to study "frog kick."
She noticed that the frog kicked a little when the switch was closed but kicked violently when
the switch was opened. Model the frog as a resistor (Rfrog = 1000N). Assume that switch
has been closed for a long time.
a) Compute the initial inductor current under DC conditions.
b) At t = Os the switch is opened. Compute inductor current for t > 0.
c) What is voltage applied to frog for t > 0? What could be a possible reason for the frog's
violent kick?
