Essay on Electric Current

Electronic electroscope

An electroscope is the instrument used to detect charged bodies. Here, an electronic version of the scope that is more sensitive as compared to its conventional counterpart and which helps indicate the polarity of charge has been described. This circuit consumes very low quiescent power and reliably indicates charge induction and detection. The polarity of […]

Lightning arresters

A lightning arrester Is a device used on electrical power systems and telecommunications systems to protect the Insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the […]

Physics of Xray

The X-Ray imagination system has one map. and that is to supply a changeless flow of negatrons that are strong plenty to bring forth and x-ray beam to make an image. There are many different sizes and types of imaging systems but no affair what system you use. every type will hold three chief subdivisions. […]

Self induction and mutual induction

CHAPTER-1 1. Initiation 1.1 Introduction Induction is the belongings of electrical circuits incorporating spirals in which a alteration in the electrical current induces an electromotive force ( voltage ) . This value of induced voltage opposes the alteration in current in electrical circuits and electric current ‘I ‘ produces a magnetic field which generates magnetic […]

Electric Current

“Battery-Resistor”: Check “show battery” and “show cores”, watch what happens, adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery, label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons are […]
