The potential outside the grounded sphere will be determined only by the distribution of charge outside the sphere and will be independent of the charge distribution inside the sphere. If we assume for simplicity (without loss of generality) that the inner charge lies on the z-axis, then the induced charge density will be simply a function of the 78:, the electric field is uniquely determined if the total charge on each conductor is given. Possessing knowledge of either the electric potential or the electric field and the corresponding boundary conditions we can swap the charge distribution we are considering for one with a configuration that is easier to analyze, so long as it satisfies 478: 2623: 2866:

If the dipole is pictured as two large charges separated by a small distance, then the image of the dipole will not only have the charges modified by the above procedure, but the distance between them will be modified as well. Following the above procedure, it is found that

It can be shown that the resulting electric field inside the dielectric containing the particle is modified in a way that can be described by an image charge inside the other dielectric. Inside the other dielectric, however, the image charge is not present. 2153:{\displaystyle 4\pi \varepsilon _{0}V(\mathbf {r} )={\frac {q}{|\mathbf {r} _{1}|}}+{\frac {(-qR/p)}{|\mathbf {r} _{2}|}}={\frac {q}{\sqrt {r^{2}+p^{2}-2\mathbf {r} \cdot \mathbf {p} }}}+{\frac {(-qR/p)}{\sqrt {r^{2}+{\frac {R^{4}}{p^{2}}}-{\frac {2R^{2}}{p^{2}}}\mathbf {r} \cdot \mathbf {p} }}}} 638: 902:{\displaystyle {\begin{aligned}Q_{t}&=\int _{0}^{2\pi }\int _{0}^{\infty }\sigma \left(\rho \right)\,\rho \,d\rho \,d\theta \\&={\frac {-qa}{2\pi }}\int _{0}^{2\pi }d\theta \int _{0}^{\infty }{\frac {\rho \,d\rho }{\left(\rho ^{2}+a^{2}\right)^{3/2}}}\\&=-q\end{aligned}}} 295: 2418: 3356: 2746: 1316: 1648: 258:(i.e., above the conducting plate), and satisfies the boundary condition that the potential along the plate must be zero.

The method of images may be applied to a sphere as well. In fact, the case of image charges in a plane is a special case of the case of images for a sphere. Referring to the figure, we wish to find the potential
1650:. It may not even have the same sign, if the charge is placed inside the stronger dielectric material (charges are repelled away from regions of lower dielectric constant). This can be seen from the formula. 658: 473:{\displaystyle V\left(\rho ,\varphi ,z\right)={\frac {1}{4\pi \varepsilon _{0}}}\left({\frac {q}{\sqrt {\rho ^{2}+\left(z-a\right)^{2}}}}+{\frac {-q}{\sqrt {\rho ^{2}+\left(z+a\right)^{2}}}}\right)\,} 2968: 2844: 1826: 3584: 2781:, the potential outside of the sphere is given by the sum of the potentials of the charge and its image charge inside the sphere. Just as in the first case, the image charge will have charge − 2618:{\displaystyle \sigma (\theta )=\varepsilon _{0}\left.{\frac {\partial V}{\partial r}}\right|_{r=R}={\frac {-q\left(R^{2}-p^{2}\right)}{4\pi R\left(R^{2}+p^{2}-2pR\cos \theta \right)^{3/2}}}} 1750:(For the opposite case, the potential outside a sphere due to a charge outside the sphere, the method is applied in a similar way).

The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see 3510: 2907: 2775: 2403: 1848: 1748: 1020: 230: 1563: 975: 151: 256: 3604: 3406: 3379: 1568: 1327: 2846:. The potential inside the sphere will be dependent only upon the true charge distribution inside the sphere.
