For capacitors in series, 1/C_eq = 1/C1 + 1/C2. Thus, 1/C_eq = 1/2 + 1/3 = 5/6, giving C_eq = 6/5 = 1.2μF.

Inserting a dielectric material increases the capacitance of the capacitor by a factor equal to the dielectric constant of the material.

Inserting a dielectric material between the plates of a capacitor increases its capacitance due to the material's ability to reduce the electric field.

The capacitance increases when a dielectric material is introduced, as it reduces the electric field between the plates.

When a capacitor is disconnected from a battery and the plates are moved further apart, the electric potential energy increases because the capacitance decreases while the charge remains constant.

The capacitance of a spherical capacitor is given by C = 4πε₀ab/(b-a).

The dielectric constant (κ) of a vacuum is defined as 1, which serves as the reference for other materials.

When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances, thus it increases.

Introducing a dielectric material between the plates of a capacitor increases its capacitance by a factor equal to the dielectric constant (κ) of the material.

Increasing the area A of the plates increases the capacitance, as C = εA/d.

Increasing the distance between the plates of a capacitor decreases its capacitance, as capacitance is inversely proportional to the distance.

Increasing the plate area A of a parallel plate capacitor increases its capacitance, as C = ε₀A/d.

Introducing a dielectric material increases the capacitance of a capacitor by reducing the electric field between the plates.
