A capacitor of capacitance C = 7.5 μF is initially uncharged. It is connected in series with a switch of negligible resistance, a resistor of resistance R = 11.5 kΩ, and a battery which provides a potential difference of VB = 110 V (a) Calculate the current I a very long time after the switch has been closed in A. (b) Calculate the time t after which the current through the resistor is one-third of its maximum value in s. (c) Calculate the charge Q on the capacitor when the current in the resistor equals one third its maximum value in C
