Question

Choose the correct statement regarding a parallel plate capacitor. The charge of a disconnected charged capacitor increases when the plates are pulled apart. The charge of a disconnected charged capacitor remains the same when the plates are pulled apart. The capacitance is inversely proportional to the area A. The voltage of a disconnected charged capacitor remains the same when the plates are pulled apart. The voltage of a disconnected charged capacitor increases when the plates are brought closer together.

Explanation / Answer

charge will not change(remain same) as seperation of plates increases or decreases.

Charge on the capacitor is defined as

Q = C V

Here Q = charge on the capacitor

C = capacitance of the capacitor

V= voltage across the capacitor

so, this equation of charge is independent of the seperation.

as the seperation of the charged capacitor increases, voltage accross the capacitor increases and capcitance of the capacitor will decreses as same proportion as the voltage increases. So, charge on the capacitor will remain same as separation of the plates either increases or decreases.
