Capacitor question

2024 · 29 Jan · Shift 1 · Q87

JEE MainPhysicsCapacitorNumerical+4 / −1
A 16Ω16 \Omega16Ω wire is bend to form a square loop. A 9 V9 \mathrm{~V}9 V battery with internal resistance 1Ω1 \Omega1Ω is connected across one of its sides. If a 4μF4 \mu F4μF capacitor is connected across one of its diagonals, the energy stored by the capacitor will be x2μJ\frac{x}{2} \mu J2x​μJ, where x=‾x=\underline{\hspace{2cm}}x=​
