• 4 H

Answer 1

Magnetic flux of 12 microweber is linked with a coil. When current of 3 mA flows through it, the self inductance of the coil is 4 mH.

Explanation:

${\displaystyle \text{L}=\frac{\varphi }{\text{I}}}$

${\displaystyle =\frac{12\times {10}^{-6}}{3\times {10}^{-3}}}$

${\displaystyle =4\times {10}^{-3}\text{H}}$

${\displaystyle =4 \text{mH}}$
