Question

In the bridge circuit shown, the inductors are loss free. At bridge balance the value of inductance 'L' is_________mH.

• A. 40

Answer 1

The correct option is A 40
At bridge balance condition,

$\left(\omega \frac{L}{2}\right)5k=\omega \times 10\times {10}^{-3}\times 10k$

$L=40\times {10}^{-3}H$

$=40mH$
