But the experiments to which I referred in NATURE of August 7, 1937, have shown that the Biot-Savart law sometimes indicates only a small fraction of the actual force, and have therefore shown the serious incorrectness of the more general formula proposed by Dr. Drysdale.W. F. DUNTON...

EMF is an acronym used to represent electromotive force. This value represents the conversion of any form of energy into electrical energy that generates an electric current. What is the unit symbol for EMF? The unit of electromotive force (EMF) is the Volt (V), which is the same unit as...

When electric current passes through an electric element in the circuit, different charge densities occur on both sides of the element leading to electrical potential. So, the electric potential is the work that was done per unit of charge to build the difference in charge densities. What is el...
Let us imagine, Q1and Q2are the electrical charges of two objects. d is the distance between the center of the objects. The charged objects are placed in a medium of permittivity εoεr Then we can write the force ‘F’ as:
objects towards it. Now take the positive particle, and pull it off the plate against the electric field. This could be hard work because the electric force is pulling all together. The energy used for moving the particle from the plate is stored in the particle as the electrical potential ...
My theory of electrical forces is that they are called into play in insulating media by slight electric displacements, which put certain small portions of the medium into a state of distortion which, being resisted by the elasticity of the medium, produces an electromotive force ... I suppose ...
An electric field is a region of space around an electrically charged particle or object in which an electric charge would feel force.
What is Coulomb's law? Learn the formula and calculations involved in finding the electrostatic force between charged particles, with some examples.
