ELECTRIC CURRENT (I)

Is the amount of charge flowing per unit time.

CONVENTIONAL CURRENT

Flow of positive charges from the positive terminal to the negative terminal of a source of voltage.​

CONVENTIONAL CURRENT

ELECTRON CURRENT

Flow of electrons from the negative terminal to the positive terminal.

ELECTRON CURRENT

current that changes direction at a regular interval

Ex. diff. appliances in-home or school.

ALTERNATING CURRENT

current that travels in one direction

Ex. ​flashlight cells and batteries
