First we constructed the following circuit: Next we determined the Thevenin voltage (​E​Th​) by measuring the open circuit voltage ​V​ab​: Afterwards we determined the Thevenin resistance R​Th by introducing a 1 k​Ω potentiometer and adjusted the resistance until the potential difference reached half of the Thevenin voltage (​E​Th.​). Next we verified the conditions at which the circuit would undergo maximum power transfer by varying the resistance values of the potentiometer and measuring the varying voltage 4 across said potentiometer. From the voltages we deduced the power across this load resistance and graphed the resistance vs. power & the resistance vs. voltage (as shown in ​Graph 12.2​ and ​12.3​)   Results  Table 12.1 Calculated Measured % Difference E​Th 4.80V 4.83V 0.62% R​Th 2.32kΩ 2.31kΩ 0.43% Table 12.2 5 I​L I​L (Series-Parallel) 1.72mA 1.72 mA Table 12.3 V​L I​L​ (From V​L​) Original (Figure 001) 0.806V 1.7mA Thevenin Equivalent (Figure 001(b)) 0.796V 1.64mA 6
