by Tarun Agarwal 2 years ago What is Tan Delta Test : Its Principle and Modes Well, we all know that there are extensive applications of transformers across many domains. So, it is more crucial to dig deep into the concept of transformer maintenance which involves oil tests, equipment testing, and many others. More...
by Tarun Agarwal 2 years ago What is Graded Index Fiber : Working and Its Applications We know that multimode fiber is also known as step-index fiber, where the function of the radial position is the refractive index i.e, it is stable in some areas & exhibits steps at certain positions. So these are also known as graded-index...
by Tarun Agarwal 2 years ago Numerical Aperture of Optical Fiber & Its Derivation Optical fiber is a plastic or transparent fiber that is used to propagate light. The working principle of this is the total internal reflection from completely different walls. So light can be transmitted for long distances because the...
