as we know that potential difference =current*resistance.. now just take an example that one terminal has potential 10v and another terminal has 9v, then potential difference is 1v. similarly, one terminal has potential 3v and another terminal has 2v, then potential difference is 1v. my question is if the potential difference is same then current will be same then the drift velocity must be same..... but then what about more potential as a charge near more potential must have greater velocity but thats not so and why....................

my question is if the potential difference is same then current will be same then the drift velocity must be same.....


but then what about more potential as a charge near more potential must have greater velocity but thats not so and why....................

the force behind the drift velocity is the potential difference not the exact potential , so whenever the poential difference is same the current will be same.
