plz answer this numerical
In an electric circuit in series with a source of emf Eo, resistor and inductor L= 1H (Fig). If resistance Ro 1.0 Ohm, steady state current in the circuit would be Io = 1A. Then the resistance of the rheostat was changed so that the current decreases with time according to the law I = I (1-t/t), where t = 0.5 sec. Determine the resistance (in ohm) of the circuit at t=t/2 after the beginning of the current change. 18 वाली प्रेरक
