Do fibers have losses?
Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in. When you pour a liter of water in one end of a pipe, then you will always find less than a liter out of the other end. When you apply a voltage to the extreme of one wire, it doesn't matter how you do this, you will find a lesser value at the other end.
Fiber optics are no exception that the light entering one end encounters all types of obstacles and flaws, which are resulting in losses; from 2 to 10 percent for every running meter.
Why rotation of rigid bodies through finite angles not a vector? Ans) Because it does not obey one of the laws of vector algebra(law of commutativity).
The fundamental particles: Although other atomic particles are known, the three fundamental ones are: Protons. The proton has unit mass and carries a unit positive charge.
Thermonuclear reactions: The fusion reactions which require extremely high temperatures are called thermonuclear reactions. The most important thermonuclear reactions take plac

A parallel plate capacitor is made from 25 plates, each 70mmby 120mm interleaved with mica of relative permittivity 5. If the capacitance of the capacitor is 3000pF verify the
Wien displacement law: For blackbody, the product of the wavelength equivalent to the maximum radiancy and the thermodynamic temperature is a constant, the Wien displacement l
Q. Why can a DC ammeter not read AC? a) Dc ammeter can't measure ac because ac is changing continuously and periodically as well as a dc ammeter can just measure a constant cur
