1. Calculation: Using the circuit shown in Figure l, calculate the Thevenin and Norton equivalent circuit. 1) To find RTH, First transform the lower half of the bridge using A-to-Y transformation (see HWS (Lab 4)). Then use the technique shown in 4.11 (figs. 4.52 St 4.53) to simplify and find Rm. 2) To nd VTH, use A-to-Y transformation as above then add resistances in series. Remember that the resistances can be added if they share the same current (regardless of which node of the voltage source they are connected). I'\\/\\ A
