Difference Between A.C. and  D.C. concerns 
 
1)      

1)  D.C. machines are provided with commutator and brushes to get the Direct Current
2)     All current for external circuit.
3)     D.C. produce constant voltage.
4)     D.C. makes constant field .
5)     There is a danger off sparking and burning in D.C.
6)     Difficult and costly maintenance
7)        D.C. Machines are not robust .
8)     There is only opposition of resistance in D.C. circuit.
