Hello students this is the given circuit and the current flowing through the circuit is 2 .5 ampere.
00:12
So we have to calculate the potential across the circuit that is voltage b is equal to what.
00:22
So before finding the voltage we have to calculate the total resistance of the circuit.
00:28
That means we have to solve the circuit and find the total equivalent resistance.
00:33
Therefore we can able to find out the voltage drop.
00:37
So let's start the simplifying this circuit here the resistance r4 r5 r6 are connected in series.
00:48
So we can able to calculate the total resistance here here r4 r5 r6 or in series connection so therefore rs is equal to r4 plus r5 plus r6.
01:15
So the value of r4 is 57 om plus 8 6 ome plus 58 o.
01:25
This will give you rs is equal to 2 .01 oom.
01:30
So after this step, the circuit radius is to this is r1 and this is r3 and r2.
01:50
And this part of circuit will become like this.
01:55
This is rs.
02:00
Now r3 is parallel to rs.
02:03
So let's solve this parallel connection.
02:07
Here r3 parallel to rs.
02:12
So therefore 1 by rp is equal to 1 by r3 plus 1 by rs.
02:29
So this will give 2 .1 plus 31 divided by 2 .01 into 31...
