Two inductors L1 (inductance 1mH, internal resistance 3Ω) and L2 (inductance 2mH, internal resistance 4Ω), and a resistor R (resistance 12Ω) are all connected in parallel across a 5 V battery. The circuit is switched on a time t=0 The ratio of the maximum to the minimum current (Imax/Imin) drawn from the battery is
