Electric Current ( विद्युत धारा ) | Transformer|Ac Dc | Rectifier | Doubtless World |
Electric current: -An electric current is a flow of electric charge.
Conductor & Insulator: In a conductor, electric current can flow freely, in an insulator it cannot.
Ac /Dc: direct current (DC):- the electric charge (current) only flows in one direction.
Electric charge in alternating current (AC), on the other hand, changes direction periodically.
Rectifier: An electrical device which converts an alternating current into a direct Current.
Transformer: A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
