DC na nufin Direct Current, amma yana da muhimmanci ake kiran mafi “DC Current”. DC current yana nufin hawa mai tsarki a kan electric charge. A cikin DC current, electrons suka zama daga wurin bayanar zuwa wurin musamman biliyan gine tushen abu. Wannan shine mafi so kuɗi da alternating current (AC) circuits, inda current zan iya zama daga biyu na farko.
A battery yana kasance misali na DC source. A cikin battery, electrical energy yana samun shi daga chemical energy wanda aka gudanar a battery. Idan battery an haɓaka zuwa circuit, yana ba da flow mai tsarki daga terminal na negative zuwa terminal na positive na battery.
A rectifier yana amfani a kan convert alternating current zuwa direct current. Amma inverter yana amfani a kan convert direct current zuwa alternating current.
DC Current Symbol
DC current yana da flow mai tsarki. Saboda haka, symbol na DC current yana da straight line. Symbol na DC da AC current yana cika a cikin figure ta hagu.
Symbol of DC and AC Current
Farabada AC da DC Current
Electrical energy yana cikin yanayin Alternating current (AC) ko Direct current (DC). A cikin alternating current, current yana gane tushen abu 50-60 a lokaci a sekunda kamar frequency.
Muhimman farabada AC da DC ana tabbatar a cikin table ta hagu;
Alternating Current (AC)

Tushen flow na current
Idan alternating current yana zama daga circuit, yana gane tushen abu.
Idan alternating current yana zama daga circuit, yana gane tushen abu.
Frequency
Frequency na alternating current yana ce kofin da yake gane tushen abu. Idan frequency yana 50 Hz, yana cewa current yana gane tushen abu 50 a lokaci.
Electrons suka gane tushen abu daga forward zuwa backward.
Movement na Electron
Magnitude na instantaneous current yana canza a lokacin da yake zama.
Electrons yana zama kawai a forward direction.
Magnitude na current
Magnitude na instantaneous current yana canza a lokacin da yake zama.
Magnitude yana daidai a kafin da yake zama a lokacin da pure DC. Amma yana canza don pulsating DC.
Yana iya haɓaka zuwa resistive, inductive, da capacitive types of load.
