# Coulomb's Law

Written by Jerry Ratzlaff on . Posted in Electrical

Coulomb's law is the quantification of the electrostatic force between two electric charges.

## Coulomb's Law FORMULA

$$F_e = k \frac{q_1 q_2}{l^2}$$

Where:

$$F_e$$ = electrostatic force

$$q_1$$ = electric charge

$$q_2$$ = electric charge

$$l$$ = distance between the two charges

$$k$$ = constant of proportionality $$\; \left( 9 \cdot 10^9 \frac{N \cdot m^2}{C^2} \right)$$
