Coulomb's Constant

Written by Jerry Ratzlaff on . Posted in Constants

Coulomb constant, abbreviated as \(k_e, k, or K\), is the electric force constant, or the electrostatic constant, it is a proportionality constant in electrostatics equations.  When charged particles interact, a force repels or attracts the particles.

 

Coulomb's Constant Formula

\(\large{ k_e = \frac{ m_p \; l_p^3 } { q_p^2 \; t_p^2 } }\)
Symbol English Metric
\(\large{ k_e }\) = Coulmbo's constant \(\large{\frac{lbf-ft^2}{F^2}}\) \(\large{\frac{N-m^2}{C^2}}\)
\(\large{ q_p }\) = Planck charge \(\large{C}\) \(\large{A-s}\)
\(\large{ l_p }\) = Planck length \(\large{ft}\) \(\large{m}\)
\(\large{ m_p }\) = Planck mass \(\large{lbm}\) \(\large{kg}\)
\(\large{ t_p }\) = Planck time \(\large{sec}\) \(\large{s}\)
