Hello everyone, we are going to understand this question here given in the question current across 300 om, current across 300 oam register is 0 .05 ampere, current across 300 oom register i is equal to, sorry it is related by i1 that is 0 .05 ampere.
00:39
Now from the given circuit, from given circuit, from given circuit we can write potential here we can see 300 om and here r1 and r4 are parallel to each other here 300 om and 150 om are parallel to each other parallel to each other so we can write potential across 300 om and potential across 150 oom will be equal so, potential across 300 om and potential across 150 oom will be equal.
02:05
So, calculating the potential across 300 ome, so v300 is equal to i1 into r300.
02:19
So here value of i1 that is given in the question which is 0 .05 into the 0 .05.
02:25
To 300 oms.
02:28
So after calculation we will get 15 volt.
02:33
It means potential across 150 om also will be 15 ome.
02:41
I2 that is current across the 150 home register 150 upon 15 upon 150 because we know that v i is equal to v y r by r.
03:02
Here v that is 15 that is 15 that we have already calculated because in paddle combination potential always be equal and r150 that is ampere so after calculation we will get it is equal to i2 is going to 0 .1 ampere so total currents across the circuit hence total current across circuit that is i1 plus i2 now, substituting the value in this, so here we can write 0 .05 plus 0 .1...
