There are two main types of electric current based on the direction in which electric charge flows:
- Direct Current (DC)
- The flow of electric charge is in one constant direction
- The magnitude of current remains steady over time
Sources:
- Batteries
- Cells
- Solar panels
Applications:
- Mobile phones
- Laptops
- Electronic circuits
- Alternating Current (AC)
- The flow of electric charge changes direction periodically
- The magnitude of current also varies with time
Sources:
- Power stations
- Household electricity supply
Applications:
- Home appliances (fans, refrigerators, air conditioners)
- Industrial machines
Key difference:
- DC → Flows in one direction
- AC → Changes direction continuously
In simple terms:
Electric current is of two types - DC for steady flow and AC for changing flow, with AC being commonly used in homes.
