When a potential difference of 160 V is applied to the plates of an air-filled parallel-plate capacitor, the plates carry a surface charge density of 3.20 x 10 10 C/cm. What is the spacing between the plates? X Your response is off by a multiple of ten. mmFind the equivalent capacitance of the group of capacitors shown in the figure below. (Let C, = 4.60 UF, C2 = 3.60 UF, C3 = 3.10 UF, C4 = 1.80 UF, Cs = 2.50 UF, C = 6.70 UF, C7 = 6.40 JF.) + 48.0 V HF
