Electron will move towords lower potential that is A

Koushik said: (May 3, 2011)  
No you are wrong point b has more electric field intensity than point a so the force acting on electron is more in case of b than a i think you have a doubt why more electric field intensity it means the amount of work done to bring the charge from any point to b it opposes more electric field strength to bring the electron so more work has to be done i.e more potential so point b has more electric field intensity.

Raj Kishor said: (Jul 30, 2011)  
Electron will move towards the high potential i.e. B point because if there is any potential difference the elecric line of forces terminate from higher to lower potential.

Meghana said: (Aug 29, 2011)  
Current has a tendency to travel from high potetial region to low potential. Its direction is opposite to the direction of flow of electrons. Hence the electrons flow from low to potential region.

Nishtha Sharma said: (Aug 31, 2011)  
A has lower potential (we can denote it by -)
B has high potential (+)
Electron (-)will move towards B (+)
As electrons flow from low to high potential region (or in easy terms the opposite + attracts - )

Dibakar Bauri said: (Jan 24, 2012)  
Electron always flow from lower potential to higher potential and in the opposite to that of electric current.

Manish Mishra said: (Feb 19, 2012)  
Flow of almost every thing is happening from higher potential to lower electrons also.

Sanjiv Jagdev said: (Feb 23, 2012)  
A has lower potential (-)
B has high potential (+)
Electron (-)will move towards B (+)
so the answer will be B..........

Prashant Khandai said: (Jun 3, 2012)  
Lower electric potential means there are (more) electrons or negative charges and Higher potential means there are more holes or positive charges present there. So electron will move towards higher potential.

According to the question, point A is at a lower electrical potential than point B. An electron between them on the line joining them will move towards B.

Jatin Garg said: (Jun 18, 2012)  
The point A have a lower potential than B so electric field of A is lower than B so we assume that point A have negative charge and point B a positive charge and we know that electron go from A to B.

Branx said: (Jun 22, 2012)  
According to me the electron moves towards B because electron moves towards (+)charge.

Hejaz Ahmed said: (Oct 19, 2012)  
Current moves from higher potential to lower potential and the flow of electron is opposite to the flow of current that's why electrons move from lower to higher potential.

Abhishek Singh said: (Aug 31, 2013)  
At point A potential will be low means electrons would be in excess n +ve charge would be in deficit. And opposite will be the case at B where electrons are less n +ve charge is much. So just like a general case electron will obviously be attracted towards more +ve charge.

Muhammad Irfan said: (Oct 31, 2013)  
Electrons will move from high potential to low. But I think there is use any convention.

Drashti Doshi said: (Mar 12, 2014)  
It's because of the Kirchhoff's 2nd law.

Dvfd said: (Mar 12, 2014)  
Conventionally, electron moves opposite to the direction of current, direction of current is from high potential to low potential.

Ira said: (May 14, 2014)  
Electrons act opposite to the direction of current, hence if current flows from high potential to low potential then electrons flow from low potential to high potential.

Aayush said: (Jun 2, 2014)  
The answer given i.e., the electron will move towards B is correct. Some of you are confused because you might be thinking that whenever you solve a circuit then in that case the electrons moved from higher 2 lower potential but this is the conventional method.

Yogesh said: (Jun 13, 2014)  
Electric potential will always move from higher potential to lower potential.

So answer is B.

Naga said: (Jul 7, 2014)  
Current moves from high potential to low potential i.e., B to A.

And electrons move opposite to current i.e., A to B.

Alisheshtawi said: (Aug 14, 2014)  
Potential transfer from high to low but current reverse. So it's B.

Akhil said: (Aug 22, 2015)  
Electrons moves from low potential to high potential but in the case of current it will be reverse. So the answer will be B only.

Akhil said: (Aug 22, 2015)  
Electrons moves from low potential to high potential but in the case of current it will be reverse. So the answer will be B only.

Ihsan said: (Sep 2, 2015)  
Conventionally, direction of current is from high potential to low potential which is called conventional current and electronic current is always opposite to conventional current.

Amit said: (May 15, 2016)  
Electron will move towards point B because due to higher potential the sign on point B should be + and it will attract the electron toward itself.

Udayan said: (Sep 15, 2016)  
The electrons move from higher to lower electric potential so if an electron is added it moves towards B.

Nihitha said: (Apr 15, 2017)  
A positive charged ion moves from high potential to low potential. But a negatively charged ion means electron moves from low potential to high potential.

Eswar said: (May 6, 2017)  
Current flow is always opposite to electron flow. The Current direction is from high potential to low potential. And electron flow is from low potential to high potential.

Anilpilla said: (Jul 28, 2018)  
Current will flow higher potential to lower potential but we know that electron always flows in the opposite to the direction of current.

Krishna said: (Oct 5, 2018)  
A has lower potential (we can denote it by -)
B has high potential (+)
Electron (-)will move towards B (+).

As electrons flow from low to the high potential region (or in easy terms the opposite + attracts - ).
So, Answer is B.

Amartya Srivastava said: (Oct 10, 2018)  
As the electrons will flow from(-) low potential region to high potential region so it will A(-)will move towards B(+). Thus option B is correct.

Divine said: (Apr 22, 2021)  
Point a is in the state of rest but point b is in the state of motion.

Shabdita Asthana said: (Jun 27, 2021)  
The electrons will move from A to B but the electric current will move from B to A.

Electrons flow in the opposite direction to the current (conventional current).
