What is the difference between the electron flow and the conventional current in a circuit?
Original Khojo Papers practice question — not from a past board paper.
Answer
Electrons, being negatively charged, actually flow from the negative terminal of the cell to the positive terminal through the external circuit. Conventional current is defined as the flow of positive charge and is taken to go from the positive terminal to the negative, so it is opposite in direction to the electron flow.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The convention was fixed before the electron was discovered.
