Current Electricity

Overview of Current:

The Flow of  charged particles is called electric current. These particles can be positive or negative.  Basically it is a process of flowing of charge in easy wording which is controlled by some back force which compel to move electron or proton further.  This force is known as voltage or potential difference.  One basic rule to determine is that the charge always flow from high potential to low potential.  There are two Laws which are directrly concerned electricity are

  • Voltage Law
  • Current Law

Voltage Law:

”The sum of  increases in voltage is equal to the sum of decreases in any circuit”

Current Law:

” In an electron circuit, at any junction point , the total electric current in to the junction is always equal to the total electric current out”

Overview of Current Electricity:

Static electricity and electric current are two separate phenomena, both involving electric charge, and may occur simultaneously in the same object. Static electricity is a reference to the electric charge of an object and the related electrostatic discharge when two objects are brought together that are not at equilibrium. An electrostatic discharge creates a change in the charge of each of the two objects. In contrast, electric current is the flow of electric charge through an object, which produces no net loss or gain of electric charge. Although charge flows between two objects during an electrostatic discharge, time is too short for current to be maintained.
