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.
Show the mathematical relation connecting n,u,v and R for refraction at a spherical surface concave towards a point object in a denser medium producing a virtual image.
How long does it take for the water to reach the boiling point? An iron boiler of mass 230 kg contains 830 kg of water at 18C. A heater supplies energy at the rate of 52,000 kj/
Transition temperature It is temperature (based on the substance involved) below which a superconducting substance conducts electricity with zero resistance; as a result, the t
