SUMMARY
The electric constant, denoted as ε₀, is defined by the equation ε₀ = 1/(μ₀ * c²), where μ₀ is the magnetic constant and c is the speed of light in a vacuum. This constant plays a crucial role in Coulomb's law, which describes the electric force between two point charges as Fₑ = 1/(4πε₀) * (q₁q₂/r²). Understanding ε₀ is essential for comprehending electromagnetic interactions and the behavior of electric fields.
