Ampere's law, modified form:
The line integral of the magnetic field about a closed curve is proportional to the total of two terms: first one, the algebraic total of electric currents passing through that closed curve; and second one, the instant time rate of change of the electric flux by a surface limited by that closed curve; in differential form,
curl H = J + dD/dt,
where d/dt revel partial differentiation.
Additionally to defining electromagnetism, his equations also predict which waves can propagate by the electromagnetic field, and always would propagate at the similar speed these are electromagnetic waves; the speed can be determined by calculating (epsilon0 mu0)-1/2, which is c, the speed of light within vacuum.
Electromotive force EMF (ξ) - This is the electrical energy from an ideal battery with no internal resistance. It is also the open circuit value of a battery (no current is drawn

Air dielectric capacitors are used mainly as laboratory standards of capacitance for measurement purposes. The insulating material used in these capacitances is fused silica and th
When are intermolecular forces the strongest? Intermolecular forces (dipole-dipole, dispersion and hydrogen bonds). These forces are weaker than chemical (covalent) bonds. Thus
