Question

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

Answer 1

The general equation for voltage, field strength and distance is $E=\frac{V}{d}$

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, $E = \frac{V}{d}$ is the general equation relating voltage, field strength and distance.
