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.
describe the phenomenon of nicol prism activity
Illustrate the source of stellar energy. Describe the carbon-nitrogen cycle and proton - proton cycle occurring in stars. Write down a note on ‘Breeder reactor'.
As electric field is conservation, work done and as potential difference among two points is path independent and depends only on the position of points between which the charge is
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least 3 terminals for co
What is hall Effect? Derive an expression for it.
(i) X-rays are electromagnetic waves with wavelength lie among 0.1Å - 100Å. (ii) X-rays is invisible. (iii) They always go in a straight line with speed of light. (iv) X
If either screen or source or both are at preset distance from the diffracting device (obstacle or aperture), the diffraction is known as Fresnel type.
Q. In an ideal transformer, the transformer ratio is 1:20.The input voltage and the input power are 6 V and 600 mW respectively. Compute the primary and the secondary currents.
Radio Waves: Radio waves are electromagnetic waves with large range of wavelength from a few millimetres to many meters.
Write the commands that will create the following matrix. You can use only special matrix commands: Two cars started to move from zero position with (φ = 35o) as shown. F
