... A. Use Matlab to determine the Thevenin voltage and resistance for part A. Keep in mind that if you make all voltages sources equal zero and apply a unity current source to the “output” points, then the voltage value will = Rth. Compare to measurements and give percentage error. B. Use Matlab to det ...
