UPSEE Solved Model Paper 1

Let inductance of inductors are ‘L1’ and ‘L2’
Series Combination
Leq = L1 + L2 = 16 … (𝑖)
Perallel Combination
Leq =

L1L2

L1+L2

= 3 ... (ii)

L1L2

16

= 3
L1L2 = 48
So,
L1−L2 = √(L1+L2)2−4L1L2
= √(16)2−4×48
L1−L2 = 8 ... (iii)
From eqn (i) and eqn (iii)
L1 = 12
𝐿2 = 4
