Two inductors $$L_1$$(inductance 1 mH, internal resistance 3 Ω) and $$L_2$$ (inductance 2 mH, internal resistance 4 Ω), and a resistor R (resistance 12 Ω) are all connected in parallel across a 5 V battery. The circuit is switched on at time ¢=0. The ratio of the maximum to the minimum current $$\left(\frac{I_{max}}{I_{min}}\right)$$ drawn from the battery is
