Question

v=w/q
then
v = 100/10 rais to power minus 6
(given)
then i write
100/100 multiply 10 rais to power minus 4
Is it right​

Answer 1

Its potential is taken as zero potential. Thus the positively charged conductor has more positive potential than the earth. A  negatively charged conductor has negative potential less than that of the earth.The electric potential difference between two points in an electric circuit is the work done in moving a unit positive charge from one point to the other.

When W joule of work is done in bringing the test charge Q coulomb from infinity to the point P then the electric potential V at the point P then, V=  W/Q

The work needed to move a charge Q from infinity to a point P where electric potential is  V will be W=QV

The S.I unit of work is joule and that of the charge is coulomb.
