Big shock. One of the world’s most advanced capacitor banks (Fig. P18.84), located at the Rossendorf Research Center in Dresden, Germany, can store 50 MJ of energy and release it in less than 5 ms. This high-energy pulse of electricity is used to produce the world’s most powerful magnetic fields. 

(a) If the potential difference at the terminals of the capacitor bank is 22 kV, how much charge is on the collective plates of the capacitor bank? 

(b) What is the total capacitance of the bank?
