Question

A coil with $100$ turns has an inductance of $0.05H$ and $0.02A$ current is passed through it. Flux linked with the coil is

• A. ${10}^{-2}Wb$
• B. ${10}^{-3}Wb$
• C. ${10}^{-4}Wb$
• D. ${10}^{-5}Wb$

Answer 1

Answer: (B)

${10}^{-3}Wb$

As we know that flux = inductance x current

Hence,

Flux $\varphi =Li$
$=0.05\times 0.02$
$={10}^{-3}Wb$
