4. write a general equation for voltage (v), field strength (v/m) and distance (m) showing the relationship between these three factors.

The general equation for voltage, field strength and distance is

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, is the general equation relating voltage, field strength and distance.
