Find current through R2 resistor.(a) 3(b) 3.25(c) 3.5(d) 3.75The question was asked in examination.Question is from Mesh Analysis in chapter Methods of Analyzing Circuits of Network Theory

Answer» RIGHT CHOICE is (d) 3.75

For explanation: Applying mesh analysis, 5(I1) + 2(I1-I2) = 10. 10(I2) + 2(I2-I1) + 40 = 0. On solving, I1 = 0.5A, I2 = -3.25A. So current through R2 RESISTOR is 0.5-(-3.25) = 3.75 A.
