Introduction
This lab experiment involves choosing values of the resistors, that will enable maximum output of power in circuit two, according to the circuit connection made. The aim is determining values of the resistors that will enable increase in power up to 2.7 kilo ohms. Results were then tabulated.

Procedure
The apparatus were arranged to form a complete circuit, whereby resistor values were first were determined sequentially. The resistor value that would enable a resistivity value of 2.7 kΩ was the determined. The set up was done according to the figure below where calculations were done as
Well.
Calculations
Maximum power in the fourth resistor (R4) was determined by:
Resistance = RT
Resistance (RT) = (R1x R2)/ (R1 + R2) + R3
R1 is 0.68 kΩ and R2 is 1.50 kΩ
Therefore, Resistance = (0.68 x 1.50)/(0.68 + 1.50) + R3 = 2.7 kilo ohms
= R3 + 0.46789 = 2.7
R3= (2.7- 0.46789)
= 2.2 kΩ
Data
Discussion
According to these results, the resistors seemed to be providing relevant values that enabled successfully, the achievement of the experiment requirement, which was maximizing the output power.
Conclusion
Maximizing power enabled maximum power of 2.7 kΩ in circuit two. The used resistors provided proper values, making it possible to achieve the experiment purpose. This is because relevant resistivity was seen initially. For achievement of the required resistance, power was increased and this was successfully achieved.
