Hello everyone.
00:02
Let us do the following question.
00:03
In the question we have to find the value of current at time t.
00:07
So, firstly, we will draw the equivalent circuit for t is equal to less than 0.
00:13
This is the equivalent circuit for t is equal to less than 0.
00:17
It will solve potential at 0.
00:20
This is given as minus 30 volt.
00:23
Current at 0 this is given as 30 by 2 is equal to 15 ampere 4 t is equal to greater than 0 we have series rlc circuit we have series rlc circuit here we will get value of alpha we will get this r by 12 this is 2 into 2 l is 0 .5 this can be written as 2.
00:50
If we have to write omega node this is 1 by under the root l into c this is 1 l is 0 .5 c is 1 by 4 this equation can be written as 2 under the root 2.
01:04
Since here alpha is less than omega node since here we will say that since alpha is less than omega node so we will say we have a under dammed risk.
01:18
We have a underdammed response here...
