SUMMARY

When three capacitors with capacitances of 5 mF, 7 mF, and 2 mF are connected in series to a 1 V battery, the charge on the positive plate of the 7 mF capacitor is not equal to 7 µC. Instead, the charge on each capacitor in a series circuit is the same, and the voltage across each capacitor varies. The total capacitance for capacitors in series is calculated using the formula 1/C_total = 1/C1 + 1/C2 + 1/C3, leading to a different charge calculation than initially assumed.

PREREQUISITES
  • Understanding of capacitor basics and capacitance units (mF, µF)
  • Knowledge of series and parallel circuits
  • Familiarity with the formula C=Q/V for capacitors
  • Ability to perform calculations involving series capacitance
NEXT STEPS
  • Calculate total capacitance for capacitors in series using 1/C_total = 1/C1 + 1/C2 + 1/C3
  • Learn about voltage distribution across capacitors in series circuits
  • Explore practical applications of capacitors in electronic circuits
  • Study the effects of different configurations of capacitors on overall circuit behavior
USEFUL FOR

Electronics students, electrical engineers, and hobbyists interested in understanding capacitor behavior in series circuits.

Three capacitors of capacitance 5, 7, and 2 mF respectively, are connected in series to a 1 V battery. What is the charge on the positive plate of the 7 mF capacitor?

so if the capacitors are all connected to the battery... than all of them have to have a electrial potential of 1 v

since C=Q/V, then CV=Q

and then i have (7 x10^-6 F)*1V=Q which is 7x10^-6 C

that is what i am getting, but it seems to be wrong. please help me out

The capacitors are in series, so there is no requirement that they must have the same voltage across them.

ok i got it.
