A parallel plate capacitor is connected to a battery as shown in the figure. Consider two situations:
A: Key K is kept closed and plates of capacitors are moved apart using the insulating handle
B: Key K is opened, and plates of capacitors are moved apart using the insulating handle
Choose the correct options
a) In A: V remains the same and hence Q changes
b) In A: Q remains the same but C changes
c) In B: Q remains the same and hence V changes
d) In B: V remains the same but C changes
The answer is the options,
a) In A: V remains the same and hence Q changes
c) In B: Q remains the same and hence V changes
