1. Electric field, E = F/q

2. Electric flux = E.A

     So, the dot product of E and A will be maximum when they are parallel to each other, i.e., the angle between them is 0o.

3. Potential difference, V = W/q

                                      = joule/coulomb

                                = newton.metre/coulomb

4. Electric current, I = V/R

                                     = W/qR

                                     = joule.coulomb-1.ohm-1

                                   = joule.coulomb-1.siemen

5. q =ne

       1 = n x 1.6 x 10-19

   So, n = 6.25 x 1018 electrons.
