Discussion :: Inductors - General Questions (Q.No.4)
|Satish Kumar said: (Jul 23, 2011)|
if the inductances(resistances) are connected in parallel,the equivalent inductances(resistances) will be less than the smaller individual inductance(resistance) coz... of the formula (1/Leq)=(1/L1)+(1/L2)+......+(1/Ln)

|Ans : D
If the inductor are connected in parallel connection , then the formula for Equivalent Inductance is same as that of the Resistance.
i.e. (1/Leq)= (1/L1)+(1/L2)+(1/L3)
So (1/Leq) = (1/5m)+(1/4.3m)+(1/0.6m)
(1/Leq) = 2099.2248
Leq = 1/2099.2248 = 0.47 mH
Which is less than 0.6 mH.

|In any parallel combination of resistance or inductance the equivalent resistance or inductance is less than the least value of individual one.
Hence 0.6 is the least value in the combination of inductance in parallel.
ANS : 0.6.

|How to solve this? Please tell me.|
|Haseeb said: (Nov 16, 2020)|
|The Equation. L = L2L3 + L1L3 + L1L2/L1L2L3.|
