QUESTION
An 600 mH inductor and a 3 W resistor are connected in series with a 1200-V dc power
supply
...
(5 pts)
At what time is the current equal to 1/3 of the maximum current?

Answer
Time constant :
t = 1
...
15x10-7 s

Explanation
t = L /R
Solve for R
P = V2 /R
3 = 12002/ R
R = 480000 ohms
Now solve for time constant
t = L /R
= 600 mH /480000
t = 1
...
0025 A
Solve for Imax/3 :
Imax/3 = 0
...
00083 A
Solve for time
t = L /(V/I)
= 600 mH /( 1200/0
...
15x10-7 s
