Question

The equivalent inductance between A and B is

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

Answer 1

Answer: (A)

1 H

Answer 2

The equivalent circuit diagram is as shown in the figure

Here, all the inductances are connected in parallel hence the equivalent inductance between A and B is

$\frac{1}{L_{AB}} = \frac{1}{4} + \frac{1}{4} + \frac{1}{4} + \frac{1}{4} = \frac{4}{4} = 1$

Or (;k) $L_{AB} = 1H$
