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.
The work done by a friction force is: a) Always positive b) Always negative c) Always zero d) Either positive or negative depending upon the situation. An

Vector Direction The significance of 'direction' could be seen in the dissimilarity among velocity and speed. In physics, speed is a pure scalar or something along with a magni
In optics what is intended by the expression "constructive interference." Answer: This is factual for any kind of waves. Any time you have coherent waves of the same kind
Coupling factor: If all the flux of a primary coil links with all the turns of a secondary then 100% coupling exists. Sometimes it is more convenient to use a coupling factor
what is space charge and diffusin capacitance.
For the magnetic circuit shown in Figure find the current I in the coil needed to produce a flux of 0.45mWb in the air gap. The silicon iron magnetic circuit has a uniform cros
The greatest and least magnitude of the resultant of two forces of constant magnitude are P & Q. Proof that when the forces act at an angle of 2 alpha, their resultant is of magnit
Under particular condition, light can also suffer inelastic scattering from molecules in which it's wavelength changes.
KINEMATICS I 1. x(t) is called displacement and it denotes the position of the body at a particular time. If the displacement is positive then that body is to the right of
