So let us start with the conceive which we are going to use here for this question.
00:06
So in this question we are going to use the kirchhoff's voltage law which says that the summation of the voltage inside a closed loop is always equals to zero.
00:14
First of all let's have a look to the circuit.
00:17
So this is nothing but what the circuit which we have given here in according to question in which you can see that these are the two emf sources these are the nothing but resistance.
00:25
So we have to find the current flowing throughout each of the resistors by using this kirchhoff's law.
00:29
Okay so by using this kirchhoff's law if we apply the kvl.
00:33
So let's say this has loop 1st, this has loop 2nd.
00:36
So first of all we will apply the kvl to the 2nd loop.
00:40
So we will get 0 is equals to 12 minus of i3 into r3 minus of i2 into r2.
00:50
So while similarly if we apply the kvl for the first loop we will get 0 is equals to 9 minus of i1 r1 minus of i2 times of r2 and for the junction okay for the junction we will get the equation as i2 is equals to i1 plus i3.
01:11
So basically these are nothing but the current which is flowing through this our resistances.
01:16
Okay that is why i'm considering this here...
