SUMMARY

The discussion focuses on calculating the active and reactive effects in an AC circuit, specifically for the impedance represented by z=R2+C3. The user has already computed the voltage function u(t) and seeks validation of their calculations and understanding of the formulas involved. It is confirmed that a capacitive reactive load results in negative reactive power, while substituting an inductor for the capacitor yields positive reactive power.

PREREQUISITES
  • Understanding of AC circuit theory
  • Knowledge of impedance calculations
  • Familiarity with reactive and active power concepts
  • Basic proficiency in using phasor notation
NEXT STEPS
  • Study the principles of reactive power in AC circuits
  • Learn about the differences between capacitive and inductive loads
  • Explore the use of phasor diagrams in circuit analysis
  • Investigate the implications of negative reactive power in circuit design
USEFUL FOR

Electrical engineers, students studying circuit theory, and professionals involved in AC circuit design and analysis will benefit from this discussion.

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!
