A balacnced, three-phase, delta-connected load is supplied by a balanced, three-phase, wye-connected source over a balanced three-phase line. the source voltages are in abc phase sequence in which Van is 19.94<0 KV.
Three -phase motor is connected to a three-phase power source that has an abc phase sequence. the first load is a wye-connected, three-phase motor withdrawing a line current of 20A at a 0.8 lagging power factor.
A student standardizes his NaOH titrant solution with KHP. He performs three titrations - in each trial, the mass of KHP (204.22 g/mol) used is 1.500 g. The average amount of NaOH used in the standardization is 29.3 mL +/- 0.06 mL.
