  3. Check the method and assumptions below before using the result.

Input reference and sample values

Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.

InputFormat and unitsSample
VoltageNumeric value. Unit: V. Zero or positive.12
Plate separationNumeric value. Unit: m. Must be greater than zero.0.01

Result for these sample inputs

1200 V/m

Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.

The method, explained

Electric field = voltage difference/separation.

A WORKED EXAMPLE

Using voltage = 12 V, plate separation = 0.01 m, the result is 1200 V/m. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Ideal-component calculation for study and estimation. It does not select safe wiring, protective devices or component ratings for an installation.
