Here in this given problem, this is a complicated circuit diagram having multiple batteries and multiple resistances.
00:23
This is 16 ohm over here, this is 4 ohm.
00:30
The left side battery providing 25 volt, the right side battery providing 10 volt.
00:37
The two middle resistances 8 .0 ohm each.
00:43
So first of all we may convert them to be in parallel.
00:52
So in parallel we know they will become just 4 .00 ohm.
01:00
So modified circuit diagram, now it will be having only single middle branch having a 4 ohm resistance.
01:27
Suppose current i1 comes out of the battery providing 25 volt, this is 10 volt.
01:38
At this junction current i2 goes over here to this 10 volt battery.
01:44
So the remaining current i1 minus i2 using kirchhoff's junction rule, i1 minus i2 will be passing through this middle branch of 4 ohm.
01:56
So now using kirchhoff's voltage law to the closed loop 1, as there are two closed loops, the left side and the right side.
02:28
And kirchhoff's voltage law says algebraic sum of potential drops, potential drop takes place across the resistance...
