When a potential difference of 146 V is applied to the plates of a parallel-plate capacitor, the plates carry a surface charge density of 23.0 nC/cm2. What is the spacing between the plates? 5.62 um 9. A 0.500-V potential difference is maintained across a 1.50-m length of tungsten wire that has a cross-sectional area of 0.500mm2. What is the current in the wire? 2.98 10. Four resistors are connected to a battery as shown in the figure below.Explanation / Answer
Problem 8)
Q = C*V
Q = [(epsilon*A)/d]*146
d= epsilon*(A/Q)*146
d = (8.85*10^-12)*(1/(23*10^-5)*146
d = 5.62*10^-6m = 5.62 um
