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.
Q. Collector current I c =20 mA and base current I b = 50 A. Find current gain β of a transistor. β = I C / I B = 20 X 10 -3 / 50 X 10 -6 = 400
you are trying to measure the diameter of a circular lab table using a lab metre stick. you measure the diameter in several directions and find the following results: 98.5 cm, 1.00
Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential in the hollow conducting shell is found to be:
For the same leg strength / jumping technique weight affects how far one can jump. Acceleration = Force / Mass With more mass you can't accelerate yourself as much when you j
If W is atomic weight and N is the atomic number of an element, then: (1) Number of e -1 = W- N (2) Number of 0 n 1 = W- N (3) Number of 1 H 1 = W-N (4) Number of 0
1. How fast must an object travel for its total energy to be (a) 1% more than its rest energy and (b) 99% more than its rest energy. 2. A proton is moving with a constant speed
B-Infrared (IR) Radiant Heat Heat radiation can be achieved by using infrared (IR) radiation it penetrates about 3mm in the skin. excessive exposure can cause erythema(redden
The Josephson effect is a term given to the phenomenon of current flow across two superconductors separated by a very, thin insulating barrier. This arrangement, two superconductor
Core losses or Iron losses: These losses having of hysteresis and eddy current losses, which happen due to pulsation of flux in the core. These losses depend upon the maximum flux
