I am having problems calculating currents in time. Please help me to understand it, for example we have this circuit:
And during time in seconds.
0-1 (switch up)
1-5 (switch down)
5-6 (switch up)
6-6,5 ( switch down)
So in current circuit phase, then switch is up: I=5A, and at end time switch is down I=7,5A.
Time 0->1
I(change) = 2.5(1-1/(2.71^(-1)) = 1,58A
At zero time I = 2,5A, so I(1sec) = 2,5 + 1.58 = 4,08A (please tell if this is OK)
Now at 1-5 switch is down. At 5 sec its getting up again, so I(end) = 5A, and current I = 4,08A.
Ant tau = 1/3 (please tell if this is ok, either)
I(change) = (5 - 4,08)(1- 1/2.71^(5/ (1/3)) = ~ 0,92
So I at 5sec is I(5sec) = 4,08 + 0,92 = 5
(it gives me the same 5) something must be wrong, please help me out.
Also current should have decreased in this time.
