Calculating Charge with known voltage and Capacitance in a network

Click For Summary
SUMMARY

The discussion focuses on calculating the charge on capacitors in a network using the formula Q = VCeq, where Ceq is the equivalent capacitance. The equivalent capacitance has been established as 7.6E-6 F. Participants are prompted to calculate the charge Q4 on capacitor C4, the voltage V2 across capacitor C2, and the total energy stored in the capacitor network. The need for detailed calculations is emphasized to identify errors in the initial approach.

PREREQUISITES
  • Understanding of capacitor networks and equivalent capacitance
  • Familiarity with the formula Q = VCeq
  • Knowledge of energy stored in capacitors, given by the formula E = 0.5 * C * V^2
  • Basic algebra for manipulating equations and solving for unknowns
NEXT STEPS
  • Calculate the charge Q4 on capacitor C4 using Q = VCeq
  • Determine the voltage V2 across capacitor C2 using the relationship between charge and voltage
  • Compute the total energy stored in the capacitor network using E = 0.5 * C * V^2
  • Review the steps for calculating equivalent capacitance in series and parallel configurations
USEFUL FOR

Students and professionals in electrical engineering, physics enthusiasts, and anyone involved in circuit design or analysis who seeks to deepen their understanding of capacitor behavior in networks.

In a previous step in the problem I found the Ceq to be 7.6E-6 and know this to be the correct answer.

Q=VCeq
I used the equation above but the number I found was incorrect.

I am also asked these question and I have no idea what to do with them:

I am also asked this question:

Calculate the charge Q4, on the positive plate of capacitor C4.

Calculate the voltage V2, across capacitor C2.

What is the total energy stored in this capacitor network?

You'll have to show more of your work so that we can see what's gone wrong. Can you post your calculations?
