Hello All, My teacher gave us a problem that is driving me absolutely crazy,and my Spice simulator is supplying odd answers. His question: In acircuit with a 10V DC power supply, and a series current limiting 1kOhm resistor, and two (ideal) inductors in parallel with each other,one being 1uH and the other 10uH, will the DC currents be the exactsame in each inductor branch after reaching steady state, or will theybe less (by 10X) in the 10uH branch? If so, why should an idealinductor of ANY value have any effect whatsoever on DC current afterit reaches its steady state?Thank you!Desiree

For extra bonus points, also consider what effect, if any, there wouldbe to your final answer if there was a current flowing in a loop throughthe two inductors at time zero. (Ideal parallel inductors will happilysupport a circulating current without loss.)

DC Current in Parallel Inductors?
