Question

How do you find the average electric field?

Answer 1

Step 1: Calculate the average electric field in terms of voltage and displacement

The formula for calculating the average electric field is dividing the potential difference(voltage) by the displacement:

$\Rightarrow {\mathrm{E}}_{\mathrm{average}}=\frac{∆\mathrm{V}}{∆\mathrm{x}}$

Where, $∆\mathrm{V}$ is a change in voltage and the unit is volt, and $∆\mathrm{x}$ is the displacement and the unit is the meter.

Step 2: Calculate the electric field in terms of force and charge

An electric field at a point in space is specified by the force that would act on a charge $q_0$ when placed at that point

. $\Rightarrow \mathrm{E}=\frac{\mathrm{F}}{{\mathrm{q}}_0}$

Where $F$ is the force, and $q_0$ is the charge.
