Max Power Thevenin

00:28:16

In a Thevenin equivalent Circuit, The Load Resistance absorbs max power when the Resistance is equal to the Thevenin Equivalent Resistance. Here,in the 3rd circuit when both resistors are 2kΩ.

Power in Load resistance:

R(kΩ)    V     I(mA)   Power(mWatt)
1.00    1.00   1.00      1.0000
1.50    1.29    0.85     1.1020
2.00    1.50    0.75     1.1250
2.50    1.67    0.66     1.1111
3.00    1.80    0.60     1.0800


Octave Code for R-Power plot:
 V_th = 3;
 R_th = 2;
 
 R_load = [0.1:0.1:10];
 V_load = (R_load./(R_load.+ R_th))*V_th;
 I_load = V_load./R_load;
 P_load = V_load.*I_load;
 
 plot(R_load,P_load);
