Hello students, in this question given as a circuit is this.
00:04
Now we have to calculate the voltage v1, v2, v3 and v4.
00:09
For this we will apply the kirchhoff voltage law in the first loop.
00:14
So, after applying this 15 volt will be equal to the 2 .2 into i1 plus 4 .7 into i2 into i1 to i1 and minus 4 .7 into i3 minus 2 .2 into i2.
00:40
So, after simplification this will be 16 .9 i1 and minus 2 .2 i2 and minus 4 .7 i3 is equal to the 15, equation number 1.
01:01
Next we have to apply the kirchhoff voltage law in the loop 2.
01:06
So, the zero will be equal to the 4 .7 i2 plus 2 .2 i2 plus 2 .2 i2 and minus 2 .2 i1 and minus 2 .2 i3.
01:35
Now after simplification this minus 2 .2 i1 and plus 9 .1 i2 minus 2 .2 i3 will be equal to the zero, equation number 2.
01:55
Next we apply the kvl on the loop 3.
01:59
So, this will be equal to the minus 10 volt is equal to 2 .2 2 .2 i3 plus 4 .7 i3 minus 4 .7 i1...
