Pls solve

Dear Student,

Please find below the solution to the asked query:

We can simplify the circuit by finding the effective emf​ and effective internal resistance of the circuit.

The situation of simplification is as shown in the figure below.

1reff=1r1+1r2+1r31reff=11+12+111reff=2+121reff=52reff=25 Ω

and the effective emf is,

εemfreff=ε1r1+ε2r2+ε3r3εemfreff=31-42+61εemf25=3-2+6εeff=25×7εeff=145 ΩSo,I=1451.6+0.4=1410=1.4 ASo,VR=IR=1.4×1.6=2.24 VSo,2.24=3-I1I1=0.76 A2.24=-4-2I2I2=-6.242 A=-3.12 A2.24=6-I3I3=3.76 A

So, the current in the 2 ohm resistor flows in the opposite direction to the direction shown in the figure.​
