Engineering Active and reactive effect in AC circuit

Click For Summary
The discussion focuses on computing the reactive and active effects in an AC circuit with the impedance z=R2+C3. The user has already calculated the voltage u(t) but seeks confirmation on the correctness of their formulas and calculations. It is clarified that a capacitive reactive load results in negative reactive power, while an inductive load yields positive reactive power. The user expresses understanding after this explanation. Overall, the conversation emphasizes the distinction between capacitive and inductive effects in AC circuits.

Homework Statement
Compute the active and reactive effect that is obtained in the load R2-C3.
Relevant Equations
P=RIe^2; Q=XIe^2
Hi, I am once again asking for help regarding a AC circuit problem. This time I need to compute reactive and active effect for z=R2+C3 in the below circuit. I have already computed u(t) from before so that solves half of the problem. I am unsure if I have done the calculations correct, not much if the number-computations are correct, but if the different formulas all make sense. And if the reactive effect can be negative?

The equations look OK to me.

If the reactive load is capacitive, then the reactive power will be negative. If you substitute an inductor for the capacitor, then the reactive load will be positive.
 
Okay now I understand. Thanks!
 

Thread 'AM-AM and AM-PM graph generation in LTSpice'

Greetings to all, I am writing with a question regarding graph generation in LTSpice. I am using LTSpice XVII and am trying to plot AM-AM and AM-PM characterization for a power amplifier, but I haven't been successful yet, likely due to my lack of practice with this specific analysis. I have been using a square wave input at 8.2 MHz as the voltage waveform for my power amplifier. It is said that for a switching amplifier like Class-D, the AM-AM / AM-PM (amplitude-to-amplitude and...

Thread 'How do I determine the resistance for RLC low pass filter?'

Hi, I am trying to build a RLC low pass filter that atenuates the frequency below 4500 Hz. However, I have encountered some problem when choosing the correct R to work with. Here is the Circuit Here is the original sound. Here is my code in Matlab function Vout = myFilterCircuit(Vin,h) n_V = length(Vin); f_7 = 4470;; % Undesired frequency h_7 = h; % delta time % These are for the constant and initialization of the variables t_7 = 0:h_7:(n_V-1)*h_7; % This is the independent variable...
