List of top Physics Questions on Capacitors

Parallel plate capacitor... separation 5 mm... mica sheet 2 mm... draws 25\% more charge. Dielectric constant is ___.
Two capacitors \( C \) and \( 2C \) charged to \( V \) and \( 2V \) respectively are connected in parallel with opposite polarity. The common potential is:

Find the equivalent capacitance between A and B, where \( C = 16 \, \mu F \). 

The capacitance of a capacitor is \( 3 \, \mu F \). If \( 108 \, \mu C \) charge is available in it, then what will be the potential difference between the plates?
A capacitor of capacitance 900 μF is charged by a 100 V battery. The capacitor is disconnected from the battery and connected to another uncharged identical capacitor such that one plate of the uncharged capacitor is connected to the positive plate and another plate of the uncharged capacitor is connected to the negative plate of the charged capacitor. The loss of energy in this process is measured as \(x \times 10^{-2}\) J. The value of \(x\) is:
