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 = Ed
V = 12 0.1 = 1.2
Potential difference, V = 1.2 V
