A capacitor of unknown capacitance is connected across a battery of V volts . The charge stored in it is 360 mu C . When potential across the capacitor is reduced by 120 V , the charge stored in it becomes 120 mu C. Calculate : What will be the charge stored in the capacitor , if the voltage applied had increased by 120 V ? |

Answer» Solution :When the potential applied is increased by 120 V , the potential becomes `V. = (V+120 )` VOLT = `(180 + 120)` volt = 300 volt `THEREFORE` Charge on capacitor `Q. = C V. = 2 MU F xx 300` volt = `600 mu C` |
