The change in voltage across a charging capacitor can be described by the following equation: V= Vo (1 - e-t/RC) where Vo is the initial or input voltage. A capacitor is charged through a 2.5kΩ resistor using a 15volt power supply. It takes 11 seconds for the potential difference across the plates to reach 10 volts. Calculate the capacitance of the capacitor in µF.
