    How to Analyze a Wheatstone Bridge with Inductances?

    Homework Statement Homework Equations Assume we have Vab. Junction Rule: I1 = I3 + I4 => I'1 = I'3 + I'4 I5 = I2 + I3 => I'5 = I'2 + I'3 Loop Rule: V - L1I'1 - L4I'4 = 0 -L1I'1 - L3I'3 + L2I'2 = 0 V - L1I'1 - L3I'3 - L5I'5 = 0 V - L2I'2 - L5I'5 = 0 The Attempt at a...
