Document Summary

Figure (a) shows the circuit from figure 5. 6- 4a after adding the short circuit and labeling the short circuit current. Also, the meshes have been identified and labeled in anticipation of writing mesh equations. Let i1 and i2 denote the mesh currents in meshes 1 and 2, respectively. In figure (a), mesh current i2 is equal to the current in the short circuit. Consequently, 2 i i= . sc. Substituting into equation 1 gives. Figure (a) calculating the short circuit current, isc, using mesh equations. To determine the value of the thevenin resistance, rt, first replace the 10 v voltage source by a. 0 v voltage source, i. e. a short circuit. The thevenin resistance will be calculated from the current and voltage of the current source as. In figure (b), the meshes have been identified and labeled in anticipation of writing mesh equations. In figure (b), mesh current i2 is equal to the negative of the current source current. i.
