Problem

Two inductors

L_1

(inductance 1 mH, internal resistance

3\,\Omega

) and

L_2

(inductance 2 mH, internal resistance

4\,\Omega

), and a resistor

R

(resistance

12\,\Omega

) are all connected in parallel across a 5 V battery. The circuit is switched on at time

t=0

. The ratio of the maximum to the minimum current (

I_{\max}/I_{\min}

) drawn from the battery is
