  2. Method of image charges - Wikipedia

    en.wikipedia.org/wiki/Method_of_image_charges

    The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.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 Dirichlet boundary conditions or Neumann boundary conditions).

    Dr. Dinesh Prasad Saklani is the director of NCERT since 2022. [2] In 2023, NCERT constituted a 19-member committee, including author and Infosys Foundation chair Sudha Murthy, singer Shankar Mahadevan, and Manjul Bhargava to finalize the curriculum, textbooks and learning material for classes 3 to 12. [4]

  4. Mass action law (electronics) - Wikipedia

    en.wikipedia.org/wiki/Mass_action_law_(electronics)

    In electronics and semiconductor physics, the law of mass action relates the concentrations of free electrons and electron holes under thermal equilibrium. It states that, under thermal equilibrium, the product of the free electron concentration and the free hole concentration is equal to a constant square of intrinsic carrier concentration .

  5. Gibbs–Donnan effect - Wikipedia

    en.wikipedia.org/wiki/Gibbs–Donnan_effect

    Gibbs–Donnan effect. The Gibbs–Donnan effect (also known as the Donnan's effect, Donnan law, Donnan equilibrium, or Gibbs–Donnan equilibrium) is a name for the behaviour of charged particles near a semi-permeable membrane that sometimes fail to distribute evenly across the two sides of the membrane. [1] The usual cause is the presence of ...

  6. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    Electrons are the charge carriers in most metals and they follow an erratic path, bouncing from atom to atom, but generally drifting in the opposite direction of the electric field. The speed they drift at can be calculated from the equation: where. is the drift velocity. is the electric current.

  7. Electrostatics - Wikipedia

    en.wikipedia.org/wiki/Electrostatics

    Electrostatics is a branch of physics that studies slow-moving or stationary electric charges. Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, ἤλεκτρον (ḗlektron), was thus the source of the word electricity.

  8. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    e. Electrostatic induction, also known as "electrostatic influence" or simply "influence" in Europe and Latin America, is a redistribution of electric charge in an object that is caused by the influence of nearby charges. [1] In the presence of a charged body, an insulated conductor develops a positive charge on one end and a negative charge on ...

    Molecular mechanics potential energy function with continuum solvent. The basic functional form of potential energy for modeling molecular systems includes intramolecular interaction terms for interactions of atoms that are linked by covalent bonds and intermolecular (i.e. nonbonded also termed noncovalent) terms that describe the long-range electrostatic and van der Waals forces.
