Difference between single phase and three phase?
Answer / s.arunachalakumar
1.SINGLE PHASE VOLTAGE IS COMPARE THEN THREE PHASE VOLTAGE
IS VERY LOW FOR EX- 1 PHASE 240V < 3 PHASE 440V.
2.THREE PHASE CAN MAKE ROTATING MAGNATIC FIELD. BUT SINGLE
PHASE CAN NOT MAKE ROTATING MAGNATIC FIELD.
3.IN THREE PHASE IS PHASE SEQUENCE.BUT SINGLE PHASE IS NOT
PHASE SEQUENCE.
