dc is an abbreviation for direct current. The term dc current is sort of wrong it's a bit like saying something twice for no reason.
It might be better to say dc electricity rather than dc current.
AnswerIn electrical engineering, it is normal to use the terms, 'd.c. current' and 'd.c. voltage', because the abbreviation, 'd.c.' is considered to be an adjective. The same is true for 'a.c.', too.
direct current
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
"dc" is direct current which is what batteries use, whereas "ac" is alternating current, which is what your household receptacle uses.
DC or direct current
A diode or rectifier converts AC to DC.
A device called an inverter is used to convert direct current (DC) to alternating current (AC). The inverter switches the direction of the current flow at a rapid rate, creating an alternating current output from the direct current input.
It makes AC ( alternating current ) . That's why it's called an alternator. A DC generator would usually be called a dynamo.
That is called "DC" or "direct current".
It's alternating current
AnswerThere is a hard rock band called AC/DC .In electrical jargon, AC is short for alternating current and DC is short for Direct current.
DC = Direct Current, so D is direct.
Direct Current.
