What is electric field strength
The force per unit charge on a positive test charge at that point in the field
What are the electric field strength and force equal to between two parallel plates
F=QE
E=V/d
How do you make a stronger electric field on a metal conductor
More concentrated charge
What is electric potential
Work done per unit positive charge on a positive test charge when it is moved from infinity to that point
What is electric potential V equals to in terms of electric potential energy Ep
V=Ep/Q
