Consider two parallel metallic plates of area A and separationof distance d, one with charge Q and the other -Q. a. What is the electric field between the plates? b. What is the potential difference between the plates? c. Use the definition of capacitance and the results of (a,b)to derive a formula for the capacitance.

Explanation / Answer
electric field between the plates = E =q/0A potential difference between the plates = v = Ed =qd/0A capacitence of the capacitor c = q/v =q/qd/0A = 0A/d
