Question

what is the potential difference if work done on 10 electrons (1.6×10¹⁹) is 16 J​

Answer 1

The current is defined as rate of flow of charged particle.i.e.

i =t/Q

Hence the charge flown is,

Q =i t

Hence Q =1.0×1=1C

The charge Q is due to electrons, therefore,

Q =N×e

Here Q =1C

If N is number of electrons passing and e is the electronic charge of value 1.6×10−19

Then,

N =e/Q=1.6×10^−19/1=0.625×10^19electrons
