Tesla; T (after N. Tesla, 1870-1943):
The derived SI unit of magnetic flux density, described the magnetic flux density of magnetic flux of 1 Wb by an area of 1 m2; thus it has units of Wb/m2.
Stefan-Boltzmann law (Stefan, L. Boltzmann): The radiated power P (it is rate of emission of electromagnetic energy) of hot body is proportional to the radiating surface area,
With the help of neat & labelled diagram. Explain the principle & working of a moving coil galvanometer. What is importance of radial magnetic field.
Refraction of Light: When a ray of light in single medium meets the surface of second medium, a part of the ray enters in the second medium; this phenomenon is called as refrac
Are fibers safe? Fiber optics are passive components, hence do not use power to generate light, like the case with lamps. When light conductors only carry light from one point
Eddy currents can be briefly explained as currents produced due to induced emf in the form of eddies or ripples. Hysteresis laws mainly consists of 2 topics retentivity and coerci
(a) A current of 15A fl ows through a load having a resistance of 4Ω . Determine the power dissipated in the load. (b) A wattmeter, whose current coil has a resistance of
Hubble's law (E.P. Hubble; 1925): A relationship discovered among distance & radial velocity. Further away a galaxy is away from is, the quicker it is receding away from us. T
