The conventional current is defined as charge per unit time transported in a certain direction. The current direction is the direction of positive charge movement. A positive current is also negative charge per unit time moving in opposite direction to the corresponding positive charge. In conventional current, the type of charge carrier is irrelevant. It can also be produced by positive and negative charge carriers at the same time moving in opposite directions like currents in electrolytes or ionized gases. Electronic current is current produced by the movement of negatively charged electrons. This is usually the case in metals. When electrons produce a positive current in a certain direction, this means they are actually moving in the opposite direction.
• Electric current can be either positive or negative, but conventional current is always positive. • The conventional current for an electron flow is positive, whereas the electrical current is . • For a flow of positive charges, both the electric current and the conventional current are the same. • Since almost every electrical circuit uses an electron flow, it can be safely stated that the conventional current = – electrical current. • In conventional current, the flow of electrons is assumed as a flow of protons on the opposite direction.
