Problem #1
is= 1,000A
R1 =
0.01
Ω
Both
switches are closed
for all times: t<0 seconds.
At time t= 1 second, the
current i(t) = 0.
Switch A opens
at time: t=0 seconds, and remains open
thereafter.
At time: t=2 seconds, the switch B opens
; and remains open thereafter.
Calculate and plot
(on graphs that are neatly drawn) the current i(t), and the
voltage Vab(t), as a function of time, for values of time between: t=1 second and
t= 5 seconds. How much energy (Joules) is stored in the inductor at each of the
following times: t=0.000001 second, t=+.000001 second, t= 2 seconds, t= 5
