00:01 So here we are considering the circuit which is shown here.

00:03 So this is the circuit where the resistor r1 is given that is of 3 ohm from here and another resistor of r2 is connected which is equals to r1 that is equals to 1 ohm and here a resistor r3 is connected which is equals to 4 ohm.

00:18 Then from here we are given a battery which is connected from here with voltage that is equals to 3 volt and from here a resistor r1 is connected that is of 2 ohm and from here we are again given the battery source from here.

00:33 So this is 2 ampere current passing from this point this is point c this is point b this is point a from here.

00:40 So here we have to calculate the voltage across the circuit source that is we have to find out the value of c of v of cg.

00:51 So this is what we need to find out.

00:54 Now here for finding this value we are considering about the rth voltage that is r of ab.

00:59 So r of ab from here is equals to 3 ohm plus 4 ohm which is in parallel to 2 ohm.

01:05 Solving this here so we get the value of r of ab that is equals to 14 divided by the 9 ohm.

01:11 Now we are considering about the norton's current through this branch ab.

01:18 So norton current from the branch ab is given as i that is equals to 3 volt divided by the 2 ohm 3 minus v of c which is divided by 4.

01:27 So solving the term from here plug into the values so 2 vc minus 3 divided by 4 plus vc minus 3 divided by 3.

01:35 Solving the term from here we get the value of vc that become equals to 5 volt.

01:40 Now again i is equals to 3 of v divided by the 2 ohm plus 3v minus 5v which is divided by 4 ohm...
