(a) A 2.00-uF capacitor is connected to a 9.00-V battery. How much energy is stored in the capacitor? (b) Had the capacitor been connected to a 6.00-V battery, how much energy would have been stored?
A 1.42 mF capacitor is initially uncharged. It is connected in series with a 4.968 kΩ resistor. The combination is then connected to a 14.5 V ideal battery. How much energy will be stored in the capacitor at the moment when the current through the circuit is 0.68588969404187 mA?
200 Fair capacitor is connected to a power supply, the energy stored in the capacitor is 900 x 10% ]. While the capacitor is kept connected to the power supply, a slab of dielectric is inserted that completely fills the space bere the plates. This increases the stored energy by 180 x 10-5 J. What is the potential difference between the capacitor plates after the dielectrie is inserted?
A parallel-plate capacitor has capacitance 9.50 uF. (a) How much energy is stored in the capacitor if it is connected to a 7.00-V battery? (b) If the battery is disconnected and the distance between the charged plates doubled, what is the energy stored? (c) The battery is subsequently reattached to the capacitor, but the plate separation remains as in part (b). How much energy is stored? Need Help?

A 12.5μF capacitor is connected to a power supply that keeps a constant potential difference of 24.0 V across the plates. A piece of material having a dielectric constant of 3.75 is placed between the plates, completely filling the space between them. a.) How much energy is stored in the capacitor before the dielectric is inserted? b.) How much energy is stored in the capacitor after the dielectric is inserted? c.) By how much did the energy change during the...
A 3.0-mF capacitor initially charged to 50 V and a 8.4-mF capacitor charged to 30 V are connected to each other with the positive plate of each connected to the negative plate of the other. What is the final charge on the 8.4-mF capacitor? (Answer in mC) I posted this question earlier and the answer the person got was wrong. They said the answer was 402 mC but Webassign said it was incorrect. Any help would be much appreciated!
