List of top Physics Questions on Capacitors and Capacitance asked in TS EAMCET

A parallel plate capacitor consists of two circular plates of radii 5 cm and 10 cm. The centres of the two plates are kept on the same straight line with a separation of 'd' and the plates are completely immersed in a liquid of dielectric constant 18. If the capacitance of the capacitor immersed in the liquid is 250 pF, then the value of 'd' is

If half of the space between the plates of a parallel plate capacitor is filled with a medium of dielectric constant 4, the capacitance is \( C_1 \). If one-third of the space between the plates of the capacitor is filled with the medium of dielectric constant 4, the capacitance is \( C_2 \). If in both cases, the dielectric is placed parallel to the plates of the capacitor, then \( C_1 : C_2 \) is:

A capacitor of capacitance (4.0 ± 0.2) μF is charged to a potential of (10.0 ± 0.1) V. The charge on the capacitor is:

If the electrical potential at a point on the surface of a hollow conducting sphere of radius R is V, then the electric potential at a point which is at a distance R/3 from the centre of the sphere is:
