The electric field strength between the plates of a simple air capacitor is equal to the voltage across the plates divided by the distance between them. When a kV voltage of 64.6 V is put across the plates of such a capacitor an electric field strength of 3.4 is measured. Write an equation that will let you calculate the distance d between the plates. Your equation should contain only symbols. Be sure you define each symbol. Your equation: d = 0 Definitions of your symbols: kV 0 = 3.4 cm 0 = 64.6 V 010 X E A cm 3
