Resistor Problems: Tips, Tricks & Tough Questions

[pardesi]

can someone please post an e-link to a site having tough and conceptual resistor and capacitor problems with all the tips and trick(to solve fatsly ).

please

 

[Mr Virtual]

Yeah, I need that too.

find the equivalent resistance of a 3D cubical network, with each side of a cube having resistance R.

do the same for capacitance, assuming each side of the cube have capacitance C.

if that is too easy for you, try the same with icosahedral and dodecahedral.

* the input and output are end points of a "diagonal" in the 3D structure.

too easy if you know the trick

too easy? how about generalizing it to N-dimensional cubical network? or try a soccer ball configuration.


even better, try to solve for the resistance of a 3D lattice network in a box with a given integral length, width and height, assuming different resistance for different "directions" the resistors point at.

for instance, resistors alone the x-axis has resistance R_x, and then R_y, R_z, respectively.

if you can do all these, i would say you have a fairly well understanding of calculating resistances.:shy:

then i guess i have a "fairly well" understanding of calculating resistances
