Consider an electric circuit consisting of a coil of negligibly small inductance, consisting of N = 10 turns and with the surface area of a single loop $S=10c{m}^2,$  resistors  $R_1=R_2=3\Omega ,$  capacitor C = 2/9 F and an inductance L = 1H, connected as shown in the figure. At the moment of time t = 0 a magnetic field, parallel to the axis of the coil is switched on. The induction of the magnetic field starts growing linearly, starting from B = 0 until the maximal value B = 1T is achieved at t = 10 ms. Further the induction of the magnetic field remains constant (and equal to 1T). Given  $e^{-R_2/L\times 5ms}=0.985$
