In circuit analysis, mesh current method is used to solve for currents in planar circuits. Solving for the currents, using mesh current analysis, in the circuit given in Figure 4 would produce the following three linear equations: 30i1 + 40 + 5(i1 - i2) + 10(i1 - i3) + 90 0 2i2-905(i2-) +4(i23)196-0 20is 4(i3 - i2) + 10(is-0 Use these equations to solve for i1, i2, and iz in MATLAB 20 4 100 52 196v 40v 1 2 302 Figure 4: Mesh current method In circuit analysis, mesh current method is used to solve for currents in planar circuits.
