SUMMARY

In the discussion, two capacitors, a 40μF and a 20μF, are connected in parallel with a voltage supply of 12V. The total capacitance is calculated using the formula Ct = C1 + C2, resulting in a total capacitance of 60μF. It is established that the voltage across each capacitor in a parallel configuration remains the same at 12V, clarifying the initial confusion regarding voltage calculations.

PREREQUISITES
  • Understanding of capacitor basics, including capacitance and voltage.
  • Familiarity with the formula for total capacitance in parallel: Ct = C1 + C2.
  • Knowledge of the relationship between charge (Q), capacitance (C), and voltage (V) as expressed in Q = CV.
  • Basic understanding of energy stored in capacitors using E = 1/2CV^2.
NEXT STEPS
  • Study the effects of connecting capacitors in series versus parallel configurations.
  • Learn about the applications of capacitors in electronic circuits.
  • Explore the implications of capacitance values on circuit performance.
  • Investigate energy storage calculations for capacitors in various configurations.
USEFUL FOR

Electronics students, hobbyists, and engineers interested in understanding capacitor behavior in circuits, particularly in parallel configurations.

A 40μF capacitor and 20μF are in parallel. With 12V.
Calculate total capacitance and V on each capacitor

Q=CV E=1/2CV^2 Ct=C1+C2

I don't know where to go from here, calculating total capacitance is easy enough. Don't know how to to calculate V on each capacitor however.

Any help would be appreciated.

Hi D.J Falcon! Welcome to PF! :smile:

(try using the X2 button just above the Reply box :wink:)

If they're in parallel, isn't V the same? :confused:​
 
Yeah, of course. Perhaps I was thinking of capacitors in series?
Anyway, thanks for the help. :smile:
