Conventional Current and Real Current

Share with:


Manishankar Asks:


“What is the difference between conventional current and real current?”

 

Answer:

Conventionally. the direction of current is defined as the direction of flow of positive charges. But in real case, the flowing charges are not positive (in the case of a metal); but the current carriers are electrons which are negatively charged. So, the real current is (the word current means flow) in a direction opposite to the conventional current.

So, if you are asked to find the direction of current in  a circuit, you have to find the direction which is opposite to the direction of flow of electrons.
