Electric current is the rate of flow of electric charge. The SI Unit of electric current is the Ampere, which is equal to a flow of one coulomb per second. Electric current can be either direct or alternating. Direct Current (DC) flows in one direction only, while Alternating Current (AC) changes direction periodically. Electric currents… Read More

(DC) electricity which stands for Direct Current is a type of electrical current that flows in one direction only. It is generated by sources such as batteries and solar panels, and its polarity (positive (P) or (N) negative) remains constant. DC electricity is used in a variety of applications, including powering electronic devices, charging batteries,… Read More

Direct current (DC) is an electric current that flows in one direction only. Batteries and solar cells produce it, which powers electronic devices such as computers, phones, and lights. DC electricity was first discovered in 1820 by Italian physicist Alessandro Volta. He found that when he connected two metals with a moistened paper, an electric… Read More
