t (ms)
For the inductive circuit we can write the following equation using Kirchhoff's loop law :
V = RI + L dI/dt .........(1)
From the given graph I vs t we can write the following equation for the current as a function of time :
I = ¼ t ..........(2)
Substituting For I from (2) in (1) :
V = R(1/4 t) + L d/dt(1/4 t)
Or V = (R/4) t + L/4
Substituting R = 1 ohm, L = 400 mH = 0.4 H
V = ¼ t + 0.1 .........(3)
Voltage described by (3) will generate the current shown in the above graph. It is shown in ...
