Voltage is the potential difference between two Conductors,
for Single Phase and the fro three phase system it is the
potential Difference between three phases and the neutral
for Example in india WE have 240 Volts A C Voltage for
single phase and 415 V for 3 Phase,

Forula to determine Power, Voltage and Currents

1 Phase : P = V X I = { Power(in watts)= Voltage X Current}


3 Phase P = rootof3 X V X I cos Phi,


Power = 1.732 X Voltage X current X Power Fator
