What is the minimum value of inductance ...

What is the minimum value of inductance that can be obtained by combining three inductances of 1 H, 2 H and 3 H?

A

`4/11 H`

B

`5/11 H`

C

`6/11 H`

D

`8/11 H`

Text Solution

Verified by Experts

The correct Answer is:
C
Join them in parallel,
`1/(H_p) = 1/1+1/2+1/3=11/6 :. H_("min") = 6/11 H`.
