Find the current I2 in the circuit shown below.(a) 5.3(b) -5.3(c) 7.3(d) -7.3This question was posed to me in exam.My enquiry is from Supermesh Analysis in section Methods of Analyzing Circuits of Network Theory

Answer»

Correct OPTION is (d) -7.3

Explanation: Applying Super Mesh ANALYSIS, (10+5)I1-10(I2)-5(I3) = 50. 2(I2) + I3 + 5(I3-I1) + 10(I2-I1) = 0. I2 – I3 = 2. On solving above EQUATIONS, we get I2=-7.3A.
