we build our circuits. They are exactly opposite to each other. So are we basically utilizing how electricity behave and laying on a lie?. Our mission is to provide a free, world-class education to anyone, anywhere. The answer lies in convention. If the size of the unit decreases by 20% the% change in the numerical value is. This figure shows the difference between conventional current and electron current. Khan Academy is a 501(c)(3) nonprofit organization. describing current is this. or just plain current. Why no just to up date the information we are given? (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2020 Codrey Electronics. So before we get into these notations, we need to understand charges in electricity. We need a notation to do some calculations like in Kirchhoff’s law. Most of the electronic semiconductors are designed on the basis of conventional current. the direction of current is defined as the direction of flow of positive charges. The convention we've had Learn how your comment data is processed. As the name itself says, this notation is based on the movement of electrons. Sara. First of all Franklin assumed an electric charge which moved in the opposite direction that it should actually be doing, so he called this electric charge “negative” which means deficiency of charges and so we can consider “positive” means surplus of electric charges. current going on here. way of this electron on its path, and this is where https://www.khanacademy.org/.../intro-to-ee/v/ee-conventional-current That is called an Electron Current. What does conventional current mean? Other articles where Conventional current is discussed: electric current: …defined the current is called conventional current. 30 Oct. 2020. about current from now on, it'll always be conventional current, and in fact, we don't even need to mention conventional any more, it's just current. https://www.youtube.com/watch?v=QVhoKglhwmw, https://www.youtube.com/watch?v=WIUvBkUuMx4. why cant they just change the books?! https://www.youtube.com/watch?v=bk3RcdhoABM, Prepare for Physics oral test too during lockdown, A numerical problem from motion in 1 Dimension, Types of Errors and Errors in Combinations of Physical Quantities, National Education Policy 2020 : Introduction. https://encyclopedia2.thefreedictionary.com/conventional+current. Electron Flow is what actually happens and electrons flow out of the negative terminal, through the circuit and into the positive terminal of the source. Donate or volunteer today! Current is the direction that electrons). 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. I'm gonna flip the battery around it until the positive terminal is on the top, and I'll put my circuit over on the side over here like this. We need a notation to do some calculations like in Kirchhoff’s law. So the, the electron current is going in this direction Conventionally. electrons are in here. And I built a battery or another Definitions.net. a battery does is it pumps out energetic electrons, and they go down a hill. For example, take diode; it is like a valve which allows current to flow in only one direction. What does conventional current mean? Home » Ask Physics » Conventional Current and Real Current, “What is the difference between conventional current and real current?”. wire and inside it was, there was electrons in it, and they have a negative charge, we know they have a negative charge, and if we put a voltage on them, those electrons would move Meaning of conventional current. Answered: which theory state that every molecule of magnetic substance is a tiny magnet. However the concept of conventional current was so ingrained that it could not be altered. Conventional Current. Hence as from now we will say that electric current is a flow of positive charges even though we know that it is in fact due to the flow of electrons. The conventional current is defined as charge per unit time transported in a certain direction. In conventional current, the type of charge carrier is irrelevant. very good explanation......understood the concept atlast !!!!! thats what the problem is all about.. first we r taught that electrons r transferred and THEN we r said about the old concept of protons moving.. bt then too this helped me to get cleared.. thanks! happening inside a wire makes some sense, it's easier In the electrically stressed conductor, electric charges move from positive terminal to negative terminal of the battery. This electron travels from the negative terminal of the battery where the density of electrons is high to the positive terminal where the density of electrons is less and that’s why they get attracted towards positive terminal of the battery. But, actually this notation is scientifically not correct. We're doing our best to make sure our content is useful, accurate and safe.If by any chance you spot an inappropriate image within your search results please use this form to let us know, and we'll take care of it shortly. Perhaps the clearest way to think about this is to pretend as if movement of positive charge carriers constituted current flow. way, like that, but that's okay. The negative terminal of battery has high density of electrons. This notation is used widely by the engineers and so it is said as conventional flow notation. However it was discovered later on that in a circuit only electrons move. Out of the positive and the direction of current is defined as the direction of flow of positive charges. From now on, this is And when we talked about current, it's easiest to describe current Conventional current and electron current Identification Consider Circuit diagram with voltage source as battery and the resistance R is connected with a voltage source. Powered by WordPress / Academica WordPress Theme by WPZOOM. And if we reverse the connections, diode will not let the current pass through it. it is crazy. This has been a label since Franklin first assumed it. Conventional Current Direction. Positive terminal has surplus of electric charges and so these charges are attracted towards negative terminal of the battery where there is a deficiency of charges. what I said in that video, and I'll say again, is the convention for And we know that the this is because there are so many books that have been written based on it. when we talk about wires. It is impossible to change things that have been decided by convention long ago. The concept of current as the transfer of positive charge, so that its direction of flow is opposite to that of electrons which are negatively charged.

The concept of current is widely applied in fields such as electrical engineering, electronic engineering, electromagnetic theory and many other fields. Why do we Study electric field along axial line? they move from the negative terminal to the positive terminal of the power supply. Web. Get instant definitions for any word that hits you anywhere on the web! We have also see that an electric current is due to a flow of electrons that moves from the negative terminal to the positive terminal of the power supply.

Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow.
