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.
What do you mean by Doppler effect? Derive a mathematical expression for the apparent frequency of a note, when source of sound and observer are approaching each other.
Free Expansion process: In free expansion of gas, the gases enlarge in vacuum. Thus, work done Δw=0 In free expansion if state changes from 1 → 2 only the initial and final s
Light with a frequency of 7.5 x 10 14 Hz is able to eject electrons from the metal surface of a photocell that has a threshold frequency of 5.2 x 10 14 Hz. What stopping potentia
Q. What is ionisation potential energy? For hydrogen atom the energy necessary to remove an electron from first orbit to its outermost orbit (n=∞) is 13.6-0 = 13.6eV. This ene
two insulated charge Cu spheres A and B OF IDENTICAL size have charge qa and -3qa when they are brought in contact with each other and separated,what are new charge on them
In a single slit diffraction pattern the distance between the first minimum on left to first minimum on the right is 0.054 cm for a light of wavelength 5890 Å. Determine
It is a parameter of an insulator that defInes the maximum voltage difference that can be applied across the material before the insulator collapse and conducts.
Consider a current loop where the circulating current is I. This may be for an example of a coil carrying a current. We will assume that the current loop lies within a single plane
Displacement and Distance A simple animation showing the difference among the distance and the displacement Distance and displacement are two quantities which may seem to mean
