Coulomb's Constant

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

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