The derived unit of electric field strength is **volt per meter (V/m)**.
Electric field strength (\(E\)) is defined as the force per unit charge. It can be mathematically expressed as:
\[
E = \frac{F}{q}
\]
where:
- \(E\) is the electric field strength (in V/m),
- \(F\) is the force (in newtons, N),
- \(q\) is the charge (in coulombs, C).
Since force \(F\) is measured in newtons (N), and charge \(q\) is measured in coulombs (C), the electric field strength is expressed in newtons per coulomb (N/C). However, using the relation \(1 \text{ N/C} = 1 \text{ V/m}\), the unit of electric field strength is commonly given as **volts per meter (V/m)**.
