Basic electrical knowledge

          Electricity it is a main need of a all machine and other equipment thise is main part of the human life. So electrical basic knowledge is important like voltage and current difference and what is power and save electricity .that couse help to economy system .

Voltage= Voltage it is potential difference                         between two points like phase and neutral.the voltage meanse pressure of electricity. 

Current=current meance flow of the electron in conductor .

And it unit is Ampear.and below is formula hoy to masure current.

I=current

V=voltage

P=power (wattage of equipment)

I=V *P
