I always get confused in distinguish between ( conductor sphere and insulator sphere ) !!

what is location of charges ( only on the surface , throughout the volume , or both of them ) ?

Is E zero inside the conductor sphere ?

IF we have the both kind of spheres ( same radius ) , which one will hase the bigger capacitance ( C )

Answer #1

Condcutor has a availability of large no. of free electrons

charges are didtributed through out the Volume

while in insulators there are no free electrons

------------------------------

No, EF is nor zero inside the conductor


Capacitance is given by the formula C = 4pi eo R

so C is depening on R ans its Value is more fo conductor than insulator

    (a) We have said that Gauss’s law is always true, but only useful for calculating the electric field created by source charge distributions that are spheres, infinite straight cylinders, and infinite flat sheets, and even those cases have additional restrictions. Explain why we are limited to those distributions. Discuss what additional restrictions apply. For example, can we use Gauss’s law to find the field of a sphere whose density depends on distance r from the center? Can we do it...
