What is Electric Field Strength?
Electric Field Strength (vector symbol E) describes the magnitude and direction of the electrostatic force exerted per unit positive test charge placed at a point in space. Defined classically by Coulomb’s Law and Lorentz force formulation:
E = F ÷ q
- E: Electric field intensity (volts per meter, V/m, or newtons per coulomb, N/C).
- F: Electrostatic force experienced by the charged particle (newtons, N).
- q: Electric charge of the test particle (coulombs, C).
In potential theory and circuit analysis, electric field strength is mathematically equivalent to the negative spatial gradient of the electric potential V:
E = -∇V ⟹ for uniform fields: E = ΔV ÷ d
Dimensional Proof: Why 1 V/m Exactly Equals 1 N/C
Students and engineers frequently encounter both V/m and N/C. The two units are 100% identical in physical dimension:
1 Volt = 1 Joule ÷ 1 Coulomb = 1 (Newton × Meter) ÷ Coulomb
1 Volt ÷ Meter = [1 (Newton × Meter) ÷ Coulomb] ÷ Meter = 1 Newton ÷ Coulomb (1 N/C)
