Alternating Current Versus Direct Current By George Sereika

DC Current Direct current is the one way flow of electrical charge from a positive to a negative charge. Direct current is the one way flow of electrical charge from a positive to a negative charge. Direct current electrical charge Direct current electrical charge Batteries produce direct current. Batteries produce direct current. Batteries Direct Current is different than alternating current because the charge only flows in one direction. Direct Current is different than alternating current because the charge only flows in one direction. Thomas Edison is credited for promoting direct current.
