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
