Determine the potential difference between two charged parallel plates that are 0.10 cm apart and have an electric field strength of 12 V/cm. V

Formula for Electric Field strength, E = V/d

where V = Voltage in volts, and d = distance of separation in meters.

d = 0.1 cm, E = 12 V/cm

E = V/d = 15 / 0.025

V = E*d

V = 12 * 0.1 = 1.2

Potential difference, V = 1.2 V
