It was found that the sphere remained supraconducting in the direction of the field up to field-strengths very nearly equal to H. In the direction perpendicular to the field, supraconductivity vanishes at field strengths near 2/3 H. In other directions supraconductivity is destroyed in the interval of field-strength between 2/3 Hand H.d...

Note that instead of plates we may have conductor of different shape, for instance a sphere, a cylinder, an ellipsoid, or a conductor of an arbitrary shape. A single conductor or a combination of them may contain some charge, and to emphasize this fact, they are called capacitor. Certainly...
A uniformly charged non-conducting spherical shell is given +q charge and a point charge -q is placed as shown. The electric field lines will be View Solution A conducting sphere of radius R, carrying charge Q, lies inside uncharged conducting shell of radius 2R. If they are joined by ...
As a result of the electrostatic interaction between S1 and S2 on their surfaces induced charges Complementation to Coulomb’s law for nonzero charges Let us assume that the two spheres have nonzero charges Q1≠ 0 and Q2≠ 0. Then, if Q2/Q1=k, then from equation (9) it follows that...

A nonconducting sphere with radius a is concentric with and surrounded by a conducting spherical shell with inner radius b and outer radius c. The inner sphere has a negative charge uniformly distributed throughout its volume, while the spherical shell has no net charge. The potential V (r) ...
A method for studying the contact surface between a sphere and a plane is presented. The contact consists of a conducting sphere pressed against a metallised insulating strip. A model presented in the appendix allows one to calculate either the effective radius of contact or the electric resistance...
