The capacitor in the gure has a capacitance of 30 p F and is initially:r uncharged. The battery provides a potential difference of 170 V. After switch 5 is closed. how much charge will pass through it? Number I l Units v The plates of a spherical capacitor have rad ii 56.3 mm and 57.4 mm. (a) Calculate the capacitance. (bl What must be the plate area of a parallel-plate capacitor with the same plate separation and capacitance? n n In the gure C1: 12.5 |JF.C2 = 20.5 [JP and C3 = 275 pF. If no capacitor can withstand a potential difference of more than 130 V without failure. what is {a} the magni- tude of the maximu m potential difference that can exist between points A and B and (b) the maximum energyr that can be stored in the three-capacitor arrangement?
