Electrical Terminology

The Following are the few Electrical Terminology

Electric Current

it is the rate of flow of electrons from one point to another. Electric charge is carry by charged particles, so an electric current is a flow of charged particles. The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. And Electric current is measured by meter known as Ampere meter.

Electric Potential

Electric potential is the amount of energy require to move a unit of particle to a specific part inside the field without producing an acceleration. The voltage is measure by VOLT meter.The SI unit of Electric potential is Voltage.


The electrical resistance is a force which oppose the flow of voltage. it is the inverse quantity of electrical conductance. The SI unit of Electrical resistance is Ohm. And Calculated by Ohm Meter.


A conductor is an object or type of material that allows the flow of charge in one or more directions. Electrical current is generate by the flow of negatively charge electrons, positively charge holes, and positive or negative ions in some cases. The SI unit of Condctor in Moh.


Insulators are the materials or substances which resist or don’t allow the current to flow through them.Also, insulators are finding use in a variety of systems. As they do not allow the flow of heat. The property which makes insulators different from conductors is its resistivity.


The watt is the rate a source of energy uses or produces one joule during one second, so the same quantity may be referred to as a joule per second, with the symbol J/s. The more watts, the more energy used per second. It is equivalent to one volt ampere (1 V·A) or 1/746 of a horsepower.
