In the last illustration, suppose that the battery is kept connected while the plates are pulled apart. What are the answers to the parts (a), (b), (c) and (d) in that case ?

A parallel plate air capacitor is made using two square plates each of side 0.2 m, spaced 1 cm apart. It is connected to a 50V battery. If the battery is disconnected and then the plates are pulled apart to a separation of 2 cm, what are the answers to the above parts ? S

A parallel plate air capacitor is made using two plates 0.2 m square , spaced 1 cm apart . It is connected to a 50V battery. (a) what is the capacitance ? (b) what is the charge one each plane ? (c) what is energy stored in the capacitor ? (d) what is the electric field between the plates ? (e) If the battery is disconnected and then the plates are pulled apart to a separation of 2 cm , what are the answer to the above parts ?

A parallel plate capacitor is charged by connecting it to a battery. The battery is disconnected and the plates of the capacitor are pulled apart to make the separation between the plates twice. Again the capacitor is connected to the battery (with same polarity) then the potential difference between the plates increases when the plates are pulled apart (yes or not)

A parallel plate air capacitor is connected to a battery. After charging fully, the battery is disconnected and the plates are pulled apart to increase their separation. Which of the following statements is correct ?

A parallel - plate capacitor having plate area 20cm^2 and seperation between the plates 1.00 mm is connected to a battery of 12.0V . The plates are pulled apart to increase the separation to 2.0mm . (a ) calculate the charge flown through the circuit during the process . (b ) How much energy is absorbed by the battery during the process ? (c ) calculate the stored energy in the electric field before and after the process . (d ) Using the expression for the force between the plates , find the work done by the person polling the plates apart . (e ) Show and justify that no heat is produced during this transfer of charge as the separation is increased.
