Signals with Multiple Frequency Components

In this lab, we will calculate the magnitude response of an electrical circuit and use this information to infer the effect of the circuit on some relatively complex input signals.

 There is an 90 degree angle delay of the output signal.

As the frequency increases, the output power decreases.

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.
