1. ### the potential difference across two plates is 1.50 V. If the plates are 8.22*10^-4 m apart, what is the electric field between them?

The field can be expressed in V/m (or N/C), so one might reasonably guess that field = potential / distance here E = 1.50V / 8.22*10^-4m = 1.82*10*3 V/m (or N/C) 1820 N/C
