46. planar air condenser plates a potential difference U1 = 500 V, S = area of plates 200sm2, spacing d = 1,5 mm. After disconnecting the capacitor from the voltage source to the space between the plates is made paraffin (ε = 2). 1) Determine the potential difference between the plates of U2 after making the dielectric. Determine the capacitance of the capacitor C1 and C2 before and after the insulator; 2) Solve the problem in the case where the wax is introduced into the space between the plates when the power supply.
