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.
A circuit contains of a 10 volt battery connected in series with a 4 ohm resistor and a 6 ohm resistor. A person computes the current through the 4 ohm resistor using Ohm's Law by
A block is placed under the head of the claw hammer to aid in removing the nail. The pull on the handle is P39 N, the angle of the hammer to the vertical is P40 and the length of
A radioactive substance has a half life of 1 min. If one nuclei decays now , when will be next decay????
why michelson interferometer is called interferrometer
What is the essential effect of a magnetic field? Answer: A magnetic field is an imperceptible entity that exists in a region of space that may be void of all matter in th
Lorentz Transformation: The postulate of STR is proposed by Einstein in 1905. The two postulates are: 1. Principle of equivalence: According to this "The laws of physics
what is radiation
Energy in transmitted in space in all direction. Example : Light and sound waves propagating in space.
derive an expression for density of states and hence deduce an expression for carrier concentration of metals
