SUMMARY

This discussion focuses on calculating charge, energy, and voltage for capacitors in both series and parallel configurations. The specific circuit examples include a 200V DC series circuit with capacitors C1 = 4 μF, C2 = 8 μF, and C3 = 10 μF, as well as a 100V parallel circuit with capacitors C1 = 12 μF and C2 = 2 μF. Key calculations involve determining the combined capacitance, charge distribution in series, and energy stored in each capacitor using the formulas for capacitance and energy.

PREREQUISITES
  • Understanding of capacitor basics and their functions
  • Knowledge of series and parallel circuit configurations
  • Familiarity with capacitance formulas and energy calculations
  • Ability to perform basic electrical calculations
NEXT STEPS
  • Study the formula for combined capacitance in series: 1/C_total = 1/C1 + 1/C2 + 1/C3
  • Learn how to calculate charge using Q = C × V for capacitors
  • Explore energy stored in capacitors using the formula E = 1/2 C V²
  • Investigate charge distribution in series circuits and its implications
USEFUL FOR

Students in electrical engineering, educators teaching circuit theory, and anyone seeking to understand capacitor calculations in practical applications.

Not sure If I posted this is the correct place -Im new

hi, I am working on a college assignment. I'm on a day release program and unfortunately I missed the day where we covered this part. Please could someone help me?


The questions I need to answer are:

a) For each capacitor shown in figure 12 determine the charge, energy stored and voltage across EACH capacitor.

Figure 12 is:

200V DC series circuit with 3 capacitors C1 = 4 μF C2= 8 μF C3 = 10 μF


b) (same question different diagram)

Figure 13 is:

100v rail with two capacitors in parallel.
C1 = 12 μF
C2 = 2 μF



I have no Idea even on where to start.

If someone could help me out here I would be very great full, When I say help me out, I don't mean tell me the answers, more tell me how to find the answers.

Thanks

Grand

ifyou have 3 capacitors in series do you know how to calculate the combined capacitance? (I got 2.1μF)
Can you then calaculate the charge?
Do you know how charge is distributed amongst capacitors in series?
Hope this gets you going
