Alternating Current question

2023 · 11 Apr · Shift 2 · Q69

JEE MainPhysicsAlternating CurrentNumerical+4 / −1
A coil has an inductance of 2H2 \mathrm{H}2H and resistance of 4 Ω4 ~\Omega4 Ω. A 10 V10 \mathrm{~V}10 V is applied across the coil. The energy stored in the magnetic field after the current has built up to its equilibrium value will be ‾\underline{\hspace{2cm}}​×10−2 J\times 10^{-2} \mathrm{~J}×10−2 J.
