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.
Explain the laws of solid friction
Disadvantages of A.C. Transmission of power 1. An a.c. line needs more copper than a d.c. line. 2. The construction of an a.c. transmission line is more complex than d.c. tr

A simple electric circuit, where current is represented by the letter i. The relationship among the voltage (V), resistance (R), and current (I) is V=IR; this is called as Ohm''s L
Describe a) Potential difference between two points V, B) Intensity of electric field E. Derive the relation between them.
Harmonicmotion is considered simple if it is undamped, i.e. if it keep on to oscillate uniformly over time. Of particular interest are the frequency f or also period T of the oscil
