WHY IN THREE PHASE CABLE 440V CURRENT FLOWS IF IN ONE PHASE 230V CURRENT FLOWS ???..

Answer / rameez ajmeri

Actually Voltage is the potential difference...now the
potential difference between two Phases is 440V while the
potential difference between Line and Neutral is
230V...also the Voltage in three phase is given by root 3
into Phase voltage...

WHY IN THREE PHASE CABLE 440V CURRENT FLOWS IF IN ONE PHASE 230V CURRENT FLOWS ???..

Answer / ariel

Line Voltage = 2* Phase voltage * sin 180/no of phase

so, if line voltage = 440v

Phase Voltage = 440/ 1.732 = 254v

if 3 phase
1.732 = 2 * sin 180/3

Is This Answer Correct ?    0 Yes 7 No

WHY IN THREE PHASE CABLE 440V CURRENT FLOWS IF IN ONE PHASE 230V CURRENT FLOWS ???..

Answer / davinder yadav

If the three phase voltage is 440 V,So the single phase
voltage is 254 V.
