GATE EC 2024 Set 1 Q25 — Combinatorial Circuits

As shown in the circuit, the initial voltage across the capacitor is $10 \mathrm{~V}$ , with the switch being open. The switch is then closed at $t=0$ . The total energy dissipated in the ideal Zener diode $\left(V_{Z}=5 \mathrm{~V}\right)$ after the switch is closed (in $\mathrm{mJ}$ , rounded off to three decimal places) is $\_\_\_\_\_\_$ .
