Unformatted text preview: rule requires that L 1 ( di 1 /dt ), which is large and negative, must roughly cancel L 2 ( di 2 /dt ), which is large and positive: L 1 di 1 dt ≈ − L 2 di 2 dt . Let the common value reached by i 1 and i 2 be i , then di 1 dt ≈ ∆ i 1 ∆ t = i −E /R ∆ t and di 2 dt ≈ ∆ i 2 ∆ t = i − ∆ t . The equations above yield L 1 µ i − E R ¶ = − L 2 ( i − 0) = ⇒ i = E L 1 L 2 R 1 + L 1 R 2 = L 1 L 1 + L 2 E R ....
