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