The equivalent inductance between A and B is

Options

A. 1H
B. 4H
C. 0.8H
D. 16H

Answer

A

Explanation

The equivalent circuit diagram is as shonw in the figure,

Here, all the inductances are connected in parallel.
Hence, the equivalent inductance between A and B is
`(1)/(L_(AB))=(1)/(4)+(1)/(4)+(1)/(4)+(1)/(4)=(4)/(4)=1`
or `L_(AB)=1H`
