Pure inductance of `3.0 H` is connected as shown below. The equivalent inductance of the circuit is

Options

A. 1 H
B. 2 H
C. 3 H
D. 9 H

Answer

A

Explanation

In the given circuit, three inductances are in parallel, their equivalent inductance is given by
`(1)/(L_(eq))=(1)/(3)+(1)/(3)+(1)/(3)or L_(eq)=(3)/(3)=1H`
