उत्तर
| D. C. | A. C. | |
| Definition | In DC, the current's direction doesn't change. | In AC, the direction of the current keeps reversing periodically. |
| Load Type | DC’s load is generally resistive in nature. | AC’s load is resistive, inductive or capacitive. |
| The direction of flowing electrons | In DC, the flowing electrons are unidirectional | The direction of flow of electrons in AC is bidirectional. |
| Frequency | DC's frequency is Zero. | AC's frequency is 50 or 60 Hz. |
| Transmission | We can transmit it over a long distance with negligible losses. | We can transmit it over a long distance with few losses. |
| Purpose | Used in electroplating, electrolysis, electronic equipment, and more. | Used in factories, industries, households. |
| Passive Parameter | Resistance | Impedance |
