If 1-phase voltage is 220V, why is 3-phase 440V and not 660V ?

Last answer: Phase voltage =220v /( phase to neutral) Line voltage = 380 v ( phase to phase) Phase angle difference 120° So when two phases reach vmax +ve I.e. (+220v) + (+220v) = 440v that time due ... these event happen very fast. Hence we have 440 v only in three phase motor. √3.phase voltage= 380 v.

Last answer: B Clearly tap B is faster than the Tap A and so, the cistern will be emptied Part to be emptied = 2/5 Part emptied by (A+B) in 1 min = (1/12 – 1/20) = 5-3/60 = 2/60 =>1/30 Therefore 1/30 : 2/5 :: 1;x x= 1*2/5 *30/1 = 12mins so the tank will be emptied in 12mins.
