The differences between d.c. and a.c are as follows —
| Direct current (d.c.) | Alternating current (a.c.) |
|---|---|
| Direct current (d.c) is a current of constant magnitude flowing in one direction | Alternating current (a.c.) is the current for which both the magnitude and direction change with time. |
| The cell or a battery is a source of d.c. current. | The mains in our house or an a.c. generator are the source of alternating current (a.c.). |
