Question: Q. 3. A capacitor of unknown capacitance is connected across a battery of $V$ volt. A charge of $240 \mu \mathrm{C}$ is stored in it. When the potential across the capacitor is reduced by $80 \mathrm{~V}$, the charge stored in the capacitor becomes $80 \mu \mathrm{C}$. Calculate $V$ and the unknown capacitance. What would have been the charge in the capacitor if the voltage were increased by $80 \mathrm{~V}$ ? U [Delhi (Compt) II 2017]
