The general equation for voltage, field strength and distance is [tex]E=\frac{V}{d}[/tex]
Explanation:
Electric field is the measure of potential crossing per unit distance. In other terms we can say it as the work done to displace the charge from infinity to a point and the potential difference between them. The unit of Electric field is written as V/m, it is also known as field strength.
So the field strength is directly proportional to the potential and inversely proportional to the displacement or the distance covered by the charge. Thus, [tex]E = \frac{V}{d}[/tex] is the general equation relating voltage, field strength and distance.
