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.

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 \(\; \left( 9 \cdot 10^9 \frac{N \cdot m^2}{C^2} \right)\)
