Types of Electric Current | AC (Alternate Current) | DC (Direct Current)
All About Types of Electric Current – AC & DC Current
Current or electric current is flow or charge (electrons that are negatively charged) from one medium to another through a conductor medium like copper wire, aluminum wire, circuit, electric wiring etc.
What is the SI Unit of Current?
The SI unit of current is ampere (Unit Symbol = A). 1 Ampere = 1 Coulomb of charge passing a given point per second.
How is Electric Current Measured?
Electric current is measured using an Ammeter. Milliammeters are used to measure smaller current in milliampere. Microammeters are used to measure smaller current in microampere.
Types of Electric Current
Electric current is of 2 types – AC or Alternating Current and DC or Direct Current.
What is DC Current?
DC or Direct Current is the flow of electric charge in one direction. This is called unidirectional flow of electric charge. DC current is produced by devices like battery, thermocouple, solar cell, dynamo etc. DC current is also called galvanic current.
What is AC Current?
AC or Alternate Current is the flow of electric charge that periodically reverses direction in a waveform.
Current in Mobile Phone
The circuit of a mobile phone PCB works on DC current. The battery provides DC current to the circuit.
