91. Two flat capacitors of the same electric capacity C1 = C2 = C are connected in series to the battery and connected to a current source with electromotive force ξ. How will the potential difference U1 change on the plates of the first capacitor if the space between the plates of the second capacitor, without turning off the current source, is filled with a dielectric with a permittivity ε = 7?
