Three pure inductance each of 3 H are connected as shown in figure. The equivalent inductance of this connection between points A and B is ......

A

1 H

B

2 H

C

3 H

D

9 H

Text Solution

Verified by Experts

The correct Answer is:
A
The equivalent inductance of the connection of the given circuit is

`therefore` The equivalent inductance ,
`1/L=1/L_1+1/L_2+1/L_3`
`therefore 1/L=1/3 +1/3 +1/3`
`therefore 1/L=1 rArr L=1H`
