89. Resistance R1 = 20 ohms and an inductance coil L = 1,5 Gn having resistance R2 = 200 ohms, are connected in parallel and connected to a source of electromotive force ε = 50 V with negligible internal resistance. To determine the voltage U at the terminals of the coil through the time t = 0,20 ms after switching off the EMF source.
