i have often seen that the people answer this question by saying that it is convention .but how did this convention originate?

This originated because in the past people thought current travelled from the positive to the negative terminal, but later further research proved that it wasn't the current that flowed but the electrons that moved.

In science, around 1890s I think, starting with the Leclanche cell, the Voltaic cell, etc.... the electric battery having a (+) terminal and a (-) , when connected to a load [Any device, like an electric bulb, a resistance coil, etc] had an electric current flowing OUT from the positive terminal to the negative terminal of the battery, through the load.

Later,..... much later...When the concept of Electrons came about, being negatively charged particles, the electrons naturally were repelled from the (-) terminal of the battery and attracted towards the positive terminal. Hence the flow was now away from the (-) and IN to the (+) terminal!

Excess of electrons at one end of a conductor causes an electrical potential difference (Voltage). Electrons will flow from higher potential to lower potential until electrical equilibrium is reached. How much flows (introduce the term, current) depends on opposition to flow ( called the term residence). - Thanks from www.chennaizoom.com

it rather is in line with good judgment ,i think of. we can shop on with the theory that electric modern-day circulate takes (externally) the path to that circulate of expenses. It does no longer make any distinction. the two of the theory is valid. in easy terms the element we would desire to be very careful is that as quickly as we shop on with between the suggestions as stated above, we would desire to stick that one concept by using out the equipment (electric/electronics equipment) that's being studied or worked or utilized. word : The convention illustration has been entering prepare to maintain on with through fact earlier the introduction of the the electrical powered cost circulate that's the two valid to maintain on with.as a result, known illustration nevertheless exists to maintain on with prominently .thank you.

First Learn the MEANING of the WORD --- "CURRENT and of ELECTRONS" and only then you'll Know -- "What is the MEANING of the Word --- ELECTRICITY" ?
