Here in this question we need to find out the value of il of t where we are given that t is less than zero.
00:06
Basically we are given this circuit where this 4 ohm resistor is connected with a 12 volt battery source.
00:15
Then from here the current il naught is passing in this from here.
00:21
Let's say here is the terminal or we can say that vc voltage is here positive terminal and negative terminal.
00:27
Then again a resistor of 5 ohm is connected with a 3 ampere ammeter.
00:35
So here in this question we can say that that il of sigma or not negative is equals to from the given diagram as 3 plus 12 which is divided by 4.
00:49
So simplifying this term from here we get the value of il or not which is equals to 6 of a.
00:56
So we can say that il o negative is equals to il o inverse that is equals to 6 ampere.
01:05
So as we are considering that at t when t is approaching towards infinity which means that the switch is open here in this case.
01:15
If the switch is open then the system circuit becomes like this...
