FUN-damentals
This law describes the force between charges
What is Coulomb's Law?
Electric field lines begin here on a charge.
What is a positive charge?
The potential at 2m from a 1C charge (k = 9 x 10^9 N·m²/C²)
What is 4.5 x 10^9 volts?
This quantity increases when a dielectric is inserted between two parallel plates.
