Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Please provide an explanation. Thanks!
3. If a capacitor is connected to a battery of fixed potential while its parallel plates are being pushed a little closer together, the energy stored in the capacitor will remain constant because the voltage is unchanged.
4. A capacitor is fully charged and then disconnected from the battery. If the parallel plates are moved slightly farther apart, the electric field between them will remain constant because the charge doesn't change.
5. Replacing air between the plates of a capacitor with a dielectric, such as benzene, will reduce the electric field between the plates.

Hi I just need to know if these statements are true or false and why!! 1. Electric field lines always point from higher to lower potential, meaning that a positive test charge would then seem to "fall" in the correct direction. 2. A student measures the potential between parallel plates A and B, and the meter reading is +30 V. The student concludes that there is a charge on plate B, but none on plate A. 3. If a capacitor...

2) A 9 volt battery is connected to a parallel plate capacitor with an initial capacitance of 5 micro-farads without a dielectric. While still connected to the battery, the sheets are moved a factor of 6 times further apart and a dielectric with a dielectric constant of 1.8 is inserted between the sheets. Then, the battery is disconnected, and after the battery is disconnected, the dielectric is removed and the sheets are brought a factor of 4 times closer together....

2) A 8 volt battery is connected to a parallel plate capacitor with an initial capacitance of 7 micro-farads without a dielectric. While still connected to the battery, the sheets are moved a factor of 8 times further apart and a dielectric with a dielectric constant of 1.7 is inserted between the sheets. Then, the battery is disconnected, and after the battery is disconnected, the dielectric is removed and the sheets are brought a factor of 2 times closer together....

A capacitor is connected to a 7 volt battery which is initially does not have a dielectric. The battery is disconnected, the plates are moved further apart by a factor of 3, and a dielectric of 1.9 is inserted between its plates. The stored energy in this configuration is 400 micro-joules. What was the original value of the capacitance (of the capacitor) in micro-farads? That is, the capacitance when connected to the battery without a dielectric.

A parallel-plate capacitor has plates of area 400 cm2 and is connected across the terminals of a battery. After some time has passed, the capacitor is disconnected from the battery. When the plates are then moved 0.40 cm farther apart, the charge on each plate remains constant but the potential difference between the plates increases by 100 V. (a) What is the magnitude of the charge on each plate? (5) Determine the change in stored energy in the capacitor due...
