doh! sry, i meant to put it as an attachment, but i guess my comp skills are down there with my physics ability, lol. here it is.

capcitance again FTL :( Homework Statement All capacitors of the open circuit in Figure 3 are discharged at time t = 0, when the switch S is turned on and capacitors starts to be charged. What is the time constant \tau of the charging process? What is the charge on capacitor C2 at an...

4(r(sub b)r(sub a))/(r(sub b) - r(sub a)) and 4(r(sub d)r(sub c))/(r(sub d) - r(sub c)) are the 2 little spherical capacitors made up of spheres with radii a and b for the first one and spheres with radii c and d for the second one. no numbers are given, i have to solve C in terms of the radii...

Homework Statement A spherical capacitor is made of two insulating spherical shells with different dielectric constants k1 and k2 situated between two spherical metallic shells and separated by a vacuum gap. Geometrical dimensions of the cross-section are as shown in figure 2. Calculate the...
