Electric Potential Energy

Written by Jerry Ratzlaff on . Posted in Electrical Engineering

Electric potential energy, abbreviated as \(U_e\), also known as electrostatic potential energy, is the energy or force that is required to move a charge in resistance to an electric field.

 

Electric Potential Energy formula

\(\large{ U_e = \frac{k_e \;q_1 \;q_2}{r} }\) 
Symbol English Metric
\(\large{ U_e }\) = electric potential energy \(\large{lbf-ft}\) \(\large{J}\)
\(\large{ k_e }\) = Coulomb's constant \(\large{\frac{lbf-ft^2}{F^2}}\) \(\large{\frac{N-m^2}{C^2}}\)
\(\large{ q_1 }\) = electric charge \(\large{C}\) \(\large{A-s}\)
\(\large{ q_2 }\) = electric charge \(\large{C}\) \(\large{A-s}\)
\(\large{ r }\) = radius \(\large{ft}\) \(\large{m}\)
