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

Enter numerical value using the virtual keypad. Round off where necessary.
