After reaching steady state, an RL circuit is disconnected from the battery such that the circuitconsists of a resistor and inductor wired in series. The resulting current through the inductor (witht = 0 corresponding to the moment the battery is disconnected) is indicated below as a function oftime t for four sets of values for the resistance R and the inductance L: (1) Ro and Lo, (2) 2Ro andLo, (3) Ro and 2L。 (4) 2R0 and 2L0.Which set goes with which curve? Explain your answers.
