Other students, so in the question here it is given that v1 is equal to 18 volt, v2 is equal to 12 and value of r1 is equal to resistance 5 that is 43 ores.
00:19
R2 is equal to r6 that is equal to 138 and r3 is equal to r3 is equal to rvent.
00:28
Now, value of r2 it is also given so this is your idea right so there are some parts of question which is all back so coming to the first part here this is magnitude of voltage so can write here that magnitude of voltage across v4 is v4 so so b4 is coming out to b4 that is quite a flat.
01:09
Now we are getting the value of i4.
01:14
So we all know that i4 is equal to k2 that is divided by r5.
01:23
Now from here we get the value of equal.
01:27
So b4 is here 12 divided by 4.
01:31
By 18 plus 42 and that is multiplied by 4 4.
01:42
So here value of 4 is here.
01:46
So we'll put the value here.
01:52
Now on serving this we are getting g4 is equal to 7 .8048.

Now, coming to the second part of this question here...
