LRC circuit:what is the voltage of the capacitor when the generator is at maximum vol

Click For Summary
SUMMARY

The discussion focuses on calculating the voltage across a capacitor in an LRC circuit when the generator reaches maximum voltage. The key equations used are V=IR and V(C)=X(C)*R, where X(C) represents the capacitive reactance. The participant initially struggled with determining the impedance (Z) from frequency but ultimately resolved the issue by utilizing a triangle method for voltage calculations. The correct approach involves understanding the relationships between voltage, current, and reactance in the circuit.

PREREQUISITES
  • Understanding of LRC circuit components (inductors, resistors, capacitors)
  • Familiarity with Ohm's Law (V=IR)
  • Knowledge of capacitive reactance (X(C))
  • Basic grasp of impedance in AC circuits
NEXT STEPS
  • Study the concept of impedance in LRC circuits
  • Learn about capacitive reactance calculations
  • Explore the use of phasor diagrams in AC circuit analysis
  • Investigate the effects of frequency on circuit behavior
USEFUL FOR

Students studying electrical engineering, circuit designers, and anyone interested in understanding LRC circuit behavior and voltage calculations in AC systems.

Homework Equations



V=IR
V(C)=X(C)*R

The Attempt at a Solution



I'm having trouble with number two. I tried finding Z from the frequency and then calculating the current and mutiplying that by X(C) and got 92.9

a little typo is that I wrote V(R) twice in the diagram. The top one is V(L)
 


ohhh nvm from looking at the figure I realized how to do it. By using the triangle at the bottom!
