Question

Difference between conventional current and real current.

Answer 1

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.
