Thevenin Equivalence

LEARNING EXAMPLE

Using MATLAB to generate and plot data

DATA TO BE PLOTTED

» Rx=[0:0.1:10]'; %define the range of resistors to use

» Voc=12-6*Rx./(Rx+4); %the formula for Voc. Notice "./"

» Rth=4*Rx./(4+Rx); %formula for Thevenin resistance.

» plot(Rx,Voc,'bo', Rx,Rth,'md')

» title('USING MATLAB'), %proper graphing tools

» grid, xlabel('Rx(kOhm)'), ylabel('Volts/kOhms')

» legend('Voc[V]','Rth[kOhm]')
