00:01
So, here we have the thevenin voltage circuit diagram.
00:02
We will apply the formula and we will get the answer of the vb.
00:05
So, let's find out the vb value.
00:07
So, for that reason what we can do? we will apply the nodal analysis at nod vb.
00:22
So, we get here that is va divided by 16 plus va minus of vb divided by 4 and that's equal to 2 .5.
00:38
So, by solving this one, we will get that 5va minus of 4vb and that is equal to 40.
00:50
Let's keep this as equation number 1.
00:53
By applying the nodal analysis at nod vb, we will get this as equal to, again we will apply the nodal analysis and we will get again that is vb minus of 50 divided by 5 plus vb minus of va divided by 4 and that is equal to 0.
01:20
So, let's go ahead and we will do the same thing and we will get the equation number 2 and that is 9vb minus of 5va and that is equal to 200.
01:34
So, let's keep it as equation number 2.
01:38
Now, by solving the above equation number, equation 1 and 2, okay by solving 1 and 2, above both equations, then we will get the va, okay we are writing directly, so this is va will be 46 .4v, in the same way, the vb we will get that is 48v, right.
02:07
So, now the thevenin equivalent voltage is how much? that is 48v.
02:12
So, this is what called the thevenin voltage.
02:18
Okay, let's keep it aside and we will go further.
02:23
Okay, now we have, okay, now we have the equivalent resistance.
02:30
Now, it is time to calculate the equivalent resistance and the equivalent resistance of this, the two are both in what? series connection.
02:38
So, the resultant resistance would be 16 plus 4 and that's equal to 20 ohm.
02:45
Directly we got over here.
02:47
Now, we will go further, that is the figure, from the figure we observe that the 20 ohms, whatever we found now, that is parallel to 5 ohm, that means 20 ohm is parallel to 5 ohm, then the resultant resistance, i mean the resistance r dash would be how much? 20 plus 5 divided by, i mean 20 multiplied by 5 divided by 20 plus 5 and from here we will get the r dash and that is 4 ohm.
03:22
Okay, fine.
03:23
Okay, now we came to the partial circuit diagram, but we have to do the fully.
03:28
Okay, we have to do the full...
