Answer» The correct ANSWER is (a) 1.75A, 1.25A For explanation I WOULD say: In this circuit, we have a super mesh present. Let I1 and I2 be the currents in loops in clockwise direction. The two mesh equations are: I2-I1=3 -5I1-3I2=5 Solving these equations simultaneously, we get I1 = -1.75A and I2 = 1.25A. Since no specific direction given so currents in loop 1 and loop 2 are 1.75A and 1.25A respectively.
