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 effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at
Explain about the monochromaticity of laser. Monochromaticity: The light emitted through a laser is monochromatic, that is this is of one wavelength (colour). Although in ca
Under particular condition, light can also suffer inelastic scattering from molecules in which it's wavelength changes.
Historical development of atomic models In olden days there was an idea that all matter is made of tiny indivisible particles. When Thomson discovered electron, this idea
An engineer is making an estimate for a home owner. This owner has a small stream (Q = 1.4 cfs, T = 40°F) that is located at an elevation H = 34 ft above the owner's residence. The
There are two most popular types of PCB as under:- (a) SINGLE SIDED PCB (b) DOUBLE SIDED PCB (c) MULTI LAYERED P
Explain the differences between heat transfer mechanisms in solids, liquids, gases (conduction, convection, radiation) Explain the combinations of substances, in terms of molecula
Elastic collision : A collision is known as elastic when kinetic energy is also conserved along with the linear momentum. There is no transformation or loss of kinetic energy in th
A block of mass m is tied to a cord of length L that is pivoted at the center of a frictionless table. A second block of mass m is tied to the ?rst block also on a cord of length L
candela; cd The basic SI unit of luminous intensity described as the luminous intensity in a given direction of a source which emits monochromatic photons of frequency 540 x 1
