Two identical flat-plate air capacitors are connected in series and connected to a source of electric current with a constant EMF. A dielectric is introduced inside one of them, the dielectric constant of which is ε = 4. The dielectric fills the entire space between the plates. How and by how many times will the electrostatic field strength in this capacitor change?
