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.
