The Photo Electric Effect
Discovery, implications, and current technology
Discovery: Heinrich Hertz and Phillip Lenard
Hertz clarified Maxwell’s electromagnetic theory of light:
Proved that electricity can be transmitted in electromagnetic waves.
Established that light was a form of electromagnetic radiation.
First person to broadcast and receive these waves.
Hertz’s Spark Gap Generator:
Lenard Goes Further…
His assistant, Phillip Lenard, explored the effect further. He built his own apparatus c ....etc

ABSTRACT
Study of new and cost effective finishing processes has alwaysbeen an area of keen interest to overcome the difficulties ofexisting finishing process. Magnetic Abrasive Finishing(MAF) is a process in which a mixture of non-ferromagneticabrasives and ferromagnetic iron particles is used to dofinishing operation with the aid of magnetic force. The ironparticles in the mixture are magnetically energized using amagnetic field. The iron particles form a lightly rigid matrixin which the abrasives are trapped. This ....etc

This article describes the effect of tower displacement of two parallel transmission lines on the magnetic field distribution. Here, two parallel lines with the same working voltage and having the same span and in which the use of artificial tower displacement is made is modeled.Parallel transmission lines with different span lengths and different voltages produce tower displacements naturally and this is also modeled. Additionally, the effects like the spacing between the parallel lines, phase conductors arrangements and the transmission line ....etc

Aging Effect on Leakage Current Flow in Wooden Poles



ABSTRACT

Insulation degradation leading to leakage current flow through high voltage insulators
could result in catastrophic failures such as pole fires and damages to nearby
equipment. This paper examines the leakage current distribution originating from the
high voltage conductor to various locations through the wooden pole of various age
profiles. The specimens that are investigated in this paper range from a new sample to
an aged pole sample of ....etc

Abstract

Closed-loop servo control of a DC motor and load system using tachometer feedback is a very common industrial and research application. In the presence of finite shaft stiffness, this exercise becomes involved since flexibility introduces resonance and shaft ringing. To be able to model, predict, and eliminate these high-frequency resonance problems by means of an appropriate controller design, it is essential to have an accurate model for the entire drive system, including the tachometer.

The conventional tachometer model does n ....etc
