Question

An air-filled capacitor consists of two parallel plates, each with an area of 7.60 cm², separated by a distance of 2.20 mm. A 23.0-V potential difference is applied to these plates. 

(a) Calculate the electric field between the plates. kV/m 

(b) Calculate the surface charge density. nc/m2 

(c) Calculate the capacitance. pF (d) Calculate the charge on each plate. pC
