Here if we draw the given circuit, we will have here we have the voltage p1 and here we have the resistors which is this is r1 and this is r1 and this is r3 and here we have a point and this is b point and here we have a point and this is b point and here we have r1 and here we have r2 and this is r4.
01:00
So this is the given diagram.
01:02
Now the given values are r1 is equal to 12 kilo -oom r2 is equal to 6 kilo -oom.
01:18
R3 is equal to 25 kilo -oom and r4 is equal to 1 kilo -oom.
01:26
And v1 is equal to 24 volt.
01:32
So now the calculation of the provenin resistance.
01:37
The given diagram using the tavinine resistance, it will be equivalent to, here we'll have r1 and this is r3.
01:56
R1 and r3 and here we have a point.
02:00
And here we have c and d and this is r2 and here we have r4 and here we have v point so this is the equivalent structure we'll get now the venin resistance we know the formula r -th is equals to rac plus r -c b so this means r -th is equal to r1r3 divided by r1 plus r3 plus r2 r4 divided by r2 plus r4.
02:59
Now if we substitute the values we will get r -th is equal to 12 multiplied by 25, 12 multiplied by 25, 12 multiplied by 25.
03:15
Divided by 12 plus 25 plus 6 multiplied by 1 divided by 6 plus 1.
03:28
Now after solving this, we will get r -tavenin, which is 9 kilo -oom...
