Apparent Power & Power Factor

In this lab, we learned the use of apparent power and power factor to quantify the AC power delivered to a load and the power dissipated by the process of transmitting this power.

for  three different cases:

1. When transmission line resistance is 10 Ω (actual = 10.3 Ω)
2. When transmission line resistance is 47 Ω (actual = 47.2 Ω)
3. When transmission line resistance is 100 Ω (actual = 98.6 Ω)

This is how the circuit was connected.

After all the calculations, these are how the power dissipated when R = 10 , 47, and 100 ohms.

 case 1 R = 10ohms

 Case 2 R = 47ohms

 Case 3 R = 100 ohms

 When resistance of the transmission line R_T = 47.2 Ω, with 1uF capacitor in parallel with 1mH inductor

When resistance of the transmission line R_T = 98.6 Ω, with 1uF capacitor in parallel with 1mH inductor

When R increases, Apparent Power decreases.
