A 5-v battery is connected across the plates of a 2.0$\mu$F uncharged parallel plate capacitor. The charge on the capacitor after a long time is

Answer Details

The charge stored in a capacitor is given by the formula Q = CV, where Q is the charge, C is the capacitance, and V is the voltage across the capacitor. Initially, the capacitor is uncharged, so Q = 0. When the 5-volt battery is connected to the plates of the capacitor, the voltage across the capacitor becomes 5 V. Therefore, the charge on the capacitor becomes: Q = CV = (2.0 μF)(5 V) = 10.0 μC The charge on the capacitor will not change after a long time because a capacitor is an ideal device that stores charge without dissipating it. Therefore, the correct answer is 10.0μC.
