Current Types

• There are Two Types of electrical Flow ;

1- Direct Current ( DC)
2- Alternating Current ( AC)

1- Direct Current ( DC)

 The electrical current that only flow in one direction . You can find this case in the batteries and solar cell .

2- Alternating Current ( AC)

The electrical current is alternating in direction like its name , it mostly use in electricity production and transportation because the electricity is produced in  high range of voltage ( high voltage ) and to obtain low voltage for most application , it easier and cheaper to make this in the AC case .
