So, considering the right side of the circuit, we have here a 7 ohm resistance, here we have a 8 ohm resistance and here's another 7 ohm resistance.
00:13
So, this is 7, this is 8 and here we have a 10 ohm resistance.
00:18
This is a voltage source of 24 volts and this is node a, this is node b.
00:24
So, simplifying this circuit, first of all, this 8 ohm and this 7 ohm are in series.
00:30
So, they will sum up to 15 and that 15 would be in parallel with this 7 ohm resistor.
00:36
So, 15 and 7 would be in parallel.
00:39
So, we will simplify this circuit like this.
00:43
This is the 10 ohm resistance, this is the 24 volt source, this is node b and here we have node a and this is 7 parallel to 15.
00:55
On calculating 7 into 15 by 7 plus 15 that is the equivalent resistance, we get 4 .77 ohms.
01:04
Now, applying voltage division, by voltage division we have vab that is voltage across node a and b, it is equal to 24 that is the total voltage into resistor across a and b that is 4 .77 divided by total resistance that is 10 plus 4 .77.
01:24
So, this comes out to be 7 .75 volts...
