The correct units for electric field strength are **volts per meter (V/m)**.
This is because the electric field (E) is defined as the force per unit charge experienced by a small positive test charge. It can also be described as the change in electric potential (voltage) per unit distance.
Mathematically:
\[
E = \frac{V}{d}
\]
Where:
- **E** is the electric field strength (in V/m),
- **V** is the electric potential difference (in volts),
- **d** is the distance over which the potential difference occurs (in meters).
So, the electric field strength is measured in **volts per meter (V/m)**.
