We'd like to determine the value of certain resistors.
00:03
So we can apply our kirkoff loop law.
00:07
We have r4 i4 minus our emf, which is 85 .2 plus i5r5 equal to zero.
00:19
So we have r4 times 6 .20 minus 85 .2 plus 10 times 4 is equal to 0.
00:29
So now we can use this to solve for r4.
00:33
So we have r4 times 6 .20 minus 85 .2 plus 10 times 4 is equal to 0.
00:44
And so we get r4 is equal to 7 .29 oms.
00:51
Now we also want to find, we can continue.
00:56
We have i5, which is i4 plus i3.
01:00
So we have 10, which is 6 .20 plus i3.
01:05
So we can solve for i3.
01:09
We have 10 minus 6 .20 gives us 3 .8 amps for i3.
01:17
Now we can also find i2...
