A 18.0 V battery is connected to a 4.70 µF capacitor. How much energy is stored in the capacitor?  J

Consider the capacitor below, that is not connected to anything. The capacitor has a dielectric between its plates initially. The dielectric is slowly pulled out from between the plates. As that happens, how will the energy stored in the capacitor change? V1+ C1 O It will increase. O It will decrease. O It will stay the same.

Which of the following statements is true? O A capacitor is charged when connected to a load O Capacitors in series means: CT = C1 + C2 + ... + Cn After inserting the dielectric between the plates, the amount of charge remains the same O After inserting the dielectric between the plates, the amount of capacitance remains the same

a. A potential difference of 5.00 V is placed across a 43.1 mF capacitor. How much charge is stored in the capacitor? b. In the case of part (a), how much energy is stord in the 43.1 mF capacitor with a 5.00 V potential difference across its plates?

A parallel-plate capacitor is made of two square plates 25 cm on a side and 1.5 mm apart. The capacitor is connected to a 70-V battery. Hint a. What is the energy stored in the capacitor? Energy stored in the capacitor is b. With the battery still connected, the plates are pulled apart to a separation of 3 mm. What is the energy stored in the capacitor now? Energy now stored in the capacitor is HJ. µJ. c. This time, starting from situation in (a), with the batteries disconnected (but capacitors still charged), the plates are pulled apart to a separation of 3 mm. What is the energy stored in the capacitor now? Energy now stored in the capacitor is d. Comparing your results in (b) and (c) above, it makes sense that the energy stored in the capacitor increases in (c), because the work done in separating the plates is stored as the electrostatic potential energy. In (b), why does the energy decrease even though work is done in separating the plates? HJ. O A negative work is done in…
