Answer:
Explanation:
Work is done against a potential V to move a charge i.e. electron from positive terminal to negative terminal .
The magnitude of work is given by
[tex]W=\Delta V\cdot q[/tex]
where [tex]\Delta V=[/tex]Potential difference between the battery
q=charge on electron([tex]1.6\times 10^{19}\ C[/tex])
Answer:
W = qV
Explanation:
Let V be the potential difference of the battery, and q be the charge on the electron.
The work done in moving a charge through a potential difference V =?
Work = force * distance
Work = F.r
F = qE
But E = V / r
F = q. V / r
Work ( W ) = (qV/ r ) * r
Work = qV
Therefore the force required to move a charge through a potential difference V = qV
